SAP Fiori Tutorial, It is one thing to grasp the idea and possess theoretical understanding of any technology; it is quite another to put that knowledge to use solving problems in real time.It is not enough to be good at racing games and expect to be a Formula 1 champion. Analyzing technical problems during Fiori App configuration can also be a little challenging and time-consuming if you haven’t worked directly on real applications.

But don’t be alarmed. I, Sumit from Invenio, am here to save the day for you!

While working on intricate real-world projects involving Fiori applications, I will attempt to assist application developers (ABAP and Frontend specialists) in comprehending and using various troubleshooting tools and techniques to speed up their analysis.

When configuring any configuration, we will verify the most frequently occurring error.

Since SAP Fiori development involves a number of infrastructure components, including back-end, front-end (gateway), web dispatched, UI application, etc., resolving such issues can be difficult, annoying, and time-consuming for novices. Furthermore, problems may arise in any of these elements.

So, the crucial query is:

Where do we begin when debugging Fiori problems?

In order to initiate front-end debugging and determine whether problems are present in the front-end or back-end components, developers frequently start by using the Well-Known Function Key F12 (or right-clicking and choosing INSPECT in the browser where the Fiori App is running). There are no problems shown in the console in our sample.

2 Verifying whether there are any errors in SAP Gateway is the next step. Depending on your gateway deployment method (Hub or Embedded), it could be your front-end or back-end system.

Use transaction “/IWFND/ERROR_LOG” to confirm whether Gateway Services has received any error log reports.

Thankfully, there have been no reported issues in this instance.

In the SAP Fiori launchpad, the next step is to use transaction “/UI2/FLIA” to verify that a provided INTENT (semantic object – action pair) has been assigned to a USER.

For a user, this report offers a summary of all of their intents. It lets you see which authorization role the purpose belongs to and whether a specific person is allocated to it.

The report’s results can be filtered according to the type of device (desktop, mobile, etc.).

The personalization layer is the default layer.

The check depends on the system. Launch the report in the system whose content you wish to check.

Check to see whether “Configuration error” for semantic “ZMat” and action “Create” exists.In this

After that, see if there is a “Customization error” for the Action “Create” and the Semantic “ZMat“.The customization error in this instance is reported as follows.

To examine the error message in more detail, select the error and then click Display.

Detailed Error Message: “Launchpad ZMM / transaction / ZMM01 does not exist in client 800”.

Transaction “/UI2/FLP_CONTCHECK” is another tool that developers may utilize to confirm Fiori Launchpad content. Here, developers can filter programs using packages. Let’s examine it more closely.

Developers can also use transaction “/UI2/FLP_CONTCHECK” to verify Fiori Launchpad content.

Developers can use packages to filter apps here. Let’s give it a closer look.

Under Configuration for Custom App ZMM, no errors have been recorded.

Verify the Customization aspect as well. The error message for the Catalog ZMM, which powers our unique application, is displayed below.

In this case, it is the same error that was encountered in Step 3.

See Also: Complete SAP ABAP for S/4HANA Tutorials

We now know the problem, more or less. Now is the moment to put an end to it and win the day!

Let’s investigate the meaning behind Launchpad Role “ZMM” and Launchpad Instance “transaction” alias “ZMM01”. The Launchpad role and instance that you set up in transaction “LPD_CUST” are the same.

LPD_CUST shows that both Role and Instance are kept alive.What’s wrong if the Role and Instance are configured?

Keep in mind that Target Mapping defines the launchpad role and instance, which may be accessed using transaction /n/UI2/FLPD_CUST (Fiori launchpad designer).

After choosing the Target Mapping, select “Configure.””.

It is obvious that Target Mapping maintains Role and Instance.

What then is the problem?

Where in the configuration are we making mistakes?

To unravel this mystery, you’ll need Sherlock Holmes’s powers of observation.

Semantic mapping and launchpad settings may be closely compared, and you’ll see that the instance is kept in Lower case Target Mapping (see screenshot above).We must keep it exactly as per the LPD_CUST setting in the same scenario.

Let’s make the modification to uppercase.

Save and open the app again. Success! It was successful!

You may think the error is a monster when you receive it. However, you could think it’s all for nothing once you understand the underlying problem. For the majority of typical problems, this is true. When we know the answer, the problem always seems really straight forward.

Coding and programming the fix is simple, as we often say. The majority of the work and time is spent determining the source and fundamental cause.

The post SAP Fiori Tutorial. Part VI. How to Troubleshoot SAP Fiori Errors? first appeared on TECHNICAL GYAN GURU.

Understanding Core Data Services (CDS) Views

Core Data Services (CDS) are a framework provided by SAP for defining and consuming semantically rich data models. Unlike traditional database views, CDS views are designed to provide a higher level of abstraction and integrate seamlessly with SAP HANA’s advanced capabilities. They are essential for enabling real-time analytics and creating robust data models.

Key Features of CDS Views:

1. Semantic Layer: CDS views offer a layer of abstraction that describes the data in a business context, making it easier to interpret and use.
2. Performance Optimization: Built-in capabilities for performance optimization such as data buffering and aggregation.
3. Reusability: CDS views can be reused across various applications, reducing redundancy and ensuring consistency.

Integrating CDS Views with KPI Fiori Apps

Key Performance Indicators (KPIs) are critical for monitoring the health and performance of business processes. Fiori apps, with their user-friendly interface and real-time capabilities, provide a powerful platform for visualizing and interacting with KPIs. Integrating CDS views with KPI Fiori apps involves several key steps:

1. Defining CDS Views

To start, you need to define the CDS views that will serve as the data source for your KPIs. These views should encapsulate the relevant metrics and dimensions necessary for performance tracking.

Steps to Define CDS Views:

• Identify Requirements: Determine the specific KPIs and the data requirements for each. This includes understanding the key metrics, dimensions, and any necessary calculations.
• Create CDS Views: Use the SAP HANA Studio or Eclipse to define your CDS views. Utilize CDS annotations to enhance functionality, such as defining analytical capabilities or specifying data aggregations.

sqlCopy code@AbapCatalog.sqlViewName: 'ZMYKPI_VIEW'
@EndUserText.label: 'My KPI View'
define view Z_MY_KPI_VIEW as select from some_table {
    key field1,
    field2,
    sum(field3) as total_field3
}
group by field1, field2

2. Exposing CDS Views as OData Services

CDS views need to be exposed as OData services to be consumed by Fiori apps. This step bridges the gap between the backend data models and the frontend user interface.

Steps to Expose CDS Views:

• Create OData Service: Use SAP Gateway to create an OData service based on your CDS views. This involves defining the service, mapping the CDS view fields to the OData properties, and configuring any necessary metadata.
• Activate Service: Ensure that the OData service is activated and available for consumption. This is typically done through the SAP Gateway Service Builder (transaction SEGW).

abapCopy code@OData.publish: true
define view Z_MY_KPI_ODATA as select from Z_MY_KPI_VIEW {
    field1,
    field2,
    total_field3
}

3. Configuring KPI Tiles in Fiori Launchpad

With your OData service in place, the next step is to configure KPI tiles within the Fiori Launchpad. This involves defining how the KPIs are displayed and interacted with by end users.

Steps to Configure KPI Tiles:

• Create KPI Tile: Use the Fiori Launchpad Designer to create and configure KPI tiles. Specify the OData service as the data source and configure properties such as target values, thresholds, and visual representation.
• Set Up KPI Tile Properties: Define how the KPI values are calculated and displayed. This includes setting up alerts for threshold breaches and ensuring the KPI tiles provide actionable insights.

jsonCopy code{
    "type": "KPI",
    "dataSource": "/sap/opu/odata/sap/Z_MY_KPI_ODATA/",
    "targetValue": {
        "value": "total_field3",
        "format": "Number"
    },
    "thresholds": [
        {
            "value": "1000",
            "color": "Red"
        },
        {
            "value": "500",
            "color": "Yellow"
        }
    ]
}

4. Testing and Validation

Before rolling out your KPI Fiori apps, thorough testing is essential to ensure that the KPIs are accurate and the data is represented correctly.

Testing Checklist:

• Data Accuracy: Verify that the data in the KPI tiles matches the data from the CDS views.
• Performance: Test the performance of the OData service and KPI tiles to ensure they meet performance benchmarks.
• User Experience: Validate the usability of the KPI tiles in the Fiori Launchpad. Ensure they are intuitive and provide clear, actionable insights.

5. Continuous Monitoring and Improvement

Post-deployment, it’s crucial to continuously monitor and refine your KPIs and CDS views. This ensures that the KPIs remain relevant and the data continues to meet business needs.

Continuous Improvement Strategies:

• Monitor Performance: Regularly review the performance of KPI tiles and OData services. Optimize as necessary to maintain responsiveness and accuracy.
• Update KPIs: Adjust KPIs based on evolving business objectives and user feedback.
• Enhance Data Models: Refine CDS views to incorporate new business logic or data requirements as they emerge.

Best Practices for Using CDS Views in KPI Fiori Apps

To maximize the benefits of integrating CDS views with KPI Fiori apps, adhere to the following best practices:

1. Ensure Data Quality: High-quality data is essential for accurate KPIs. Regularly audit and cleanse data to maintain integrity.
2. Optimize Performance: Use efficient CDS view definitions and optimize OData services to ensure swift data retrieval and presentation.
3. User-Centric Design: Focus on user experience by designing KPI tiles that are intuitive and provide clear, actionable insights.
4. Documentation: Maintain thorough documentation of CDS views, OData services, and KPI configurations to facilitate easier maintenance and troubleshooting.

Conclusion

Integrating CDS views with KPI Fiori apps for Smart Business Services empowers organizations to harness the full potential of their data. By following the outlined steps and best practices, businesses can achieve enhanced visibility into performance metrics, drive better decision-making, and ultimately, foster improved operational efficiency.

Embracing this approach not only aligns with modern data management principles but also sets the stage for continued innovation and success in an increasingly data-driven world.

Order Management System (OMS) in Salesforce: Streamlining Your Sales Operations

Why are developers so fond of ‘REUSE_ALV_GRID_DISPLAY’?

The post SAP Fiori. Chapter 12: SAP Fiori Launchpad Tcode: Uses and Upkeep first appeared on TECHNICAL GYAN GURU.

Fiori is at the forefront with S/4HANA.Additionally, in order to create SAP Fiori Applications, ABAP engineers must transform into stunning butterflies in order to sip the delightful nectar of the Fiori blossoms.

Paradoxically, the comparison is ideal. For SAP ABAP Developers, there is a paradigm shift from the dull blue SAP screen to the stunning Fiori Applications. Core Data Services (CDS) is the cornerstone of S/4HANA, and one of its pillars is the ABAP Programming Model for SAP Fiori. The three SAP programming languages of the future are expected to be CDS, BOPF, and OData. Thus, it is imperative that we begin studying these subjects.

It is something you cannot escape, even if you attempt to put it off as long as you can. We are aware that change can be challenging, but we will do our best to make the switch from the outdated ABAP Develper to the newest ABAP Programmer for Fiori as easy and enjoyable as possible. We have attempted to develop a crash course tutorial series in this brief series, which is a summary of several books released by SAP Press and SCN blog entries, so you can understand it quickly. In order to assist you in comprehending, learning, and using these new areas as soon as possible, we have kept all of the articles brief, sharp, and to the point.

The book that was released states that the “ABAP Programming model for Fiori supports the development of OData services optimized for SAP HANA for SAP Fiori applications. It covers analytical, transactional, and search application scenarios and is based on Core Data Services (CDS) Views.” The two main applications of the ABAP Programming Model for SAP Fiori are Read-Only Applications and Transactional Applications.

For read-only applications, all that is required is an underlying CDS data model and application-specific analytics or search annotations. The CDS data model and related annotations are then made available as an OData service via the Service Adaptation Description Language (SADL).

The creation of a Business Object Processing Framework (BOPF) Business Object is necessary for Transactional Applications in addition to Read-Only Applications. This is because BOPF Actions, Validations, and Determinations handle additional business logic in addition to handling Create, Update, and Delete operations.

Okay, so Technicalgyanguru wouldn’t be necessary if we typed every word that was in the book.This brings us to our explanations. Real-world tasks require two different kinds of apps.First, we simply retrieve information from the

Selecting the SAP Fiori App

The journey begins with selecting the right SAP Fiori app for your needs. The SAP Fiori apps reference library is an extensive repository that provides detailed information about available Fiori apps, including functionality, prerequisites, and compatibility. To start:

Salesforce List: Your Essential Guide to Features and Functionalities

The post An Overview of SAP Fiori ABAP Programming Model – 1 first appeared on TECHNICAL GYAN GURU.

Beginners of ABAP CDS who wish to continue with the ABAP Programming Model in SAP Fiori without having to navigate and bounce between pages would find this tutorial to be helpful. However, if you want to go deeper into it, we strongly advise you to take our Core Data Services training series.

What transpires when CDS View is created?

When a CDS view is activated, two artifacts are produced: a CDS View Entity, which is a SAP HANA view on the database, and a corresponding SQL View, which is the Data Dictionary (DDIC) view in the ABAP Dictionary (@AbapCatalog.sqlViewName). With the object repository entry R3TR DDLS, just the CDS View definition is sent. Different sorts of annotations can be used to augment CDS views, which are built using CDS’s Data Definition Language (DDL), to cover various application scenarios.

Navigate to transaction SE11; the above-highlighted view will appear in the ABAP DDIC view options.

CDS Views’ naming convention

The following naming conventions are used to categorize CDS Views:

Private View (P_)

View Interface (I_)

Using Perspective (C_)

Exclusive Perspective

Private Views are made for internal use and will be accessible everywhere. Developers can build associations with this Private view or utilize it to develop CDS views.SAP does, however, advise users not to use Private views as they are not safer.In the future, certain columns might be added or removed in a way that would hinder our development because it depends on these viewpoints.

Please keep in mind that this does not mean we should never embrace their opinions. Steer clear of consumption if possible.

View of the Basic Interface

View of the Composite Interface

From a technical standpoint, Basic and Composite views differ in:

Master data is contained in Basic View, whereas both Master and Transactional data are contained in Composite View.Using I_ conventions, the Basic and Composite Interface views are identified.

View of Consumption

Interface views serve as the foundation for this view. This view serves as the data model’s pre-made solution. It is also much simpler to design and use a Fiori App using these views. It can also be used analytically; BI reports, for example, can be created. It is easy to develop if SAP already provides the Consumption views.

Key Features of CDS:

1. Semantic Layer: CDS views offer a business-oriented abstraction layer over raw data, making it easier for developers and end-users to interact with complex data structures.
2. Performance Optimization: Leveraging SAP HANA’s in-memory processing, CDS views are designed to optimize performance, enabling fast and efficient data retrieval and manipulation.
3. Reusability: CDS views can be reused across different applications, reducing redundancy and ensuring consistency in data representation.

Practical Application of CDS Views

Implementing CDS views involves several steps, each crucial for ensuring that data is modeled and utilized effectively:

1. Defining CDS Views: The first step is to define the CDS views using the ABAP Development Tools (ADT) in SAP HANA Studio or Eclipse. This involves creating a CDS view definition that specifies the data source, fields, and any necessary calculations or aggregations.

sqlCopy code@AbapCatalog.sqlViewName: 'ZMY_CDS_VIEW'
@EndUserText.label: 'My CDS View Example'
define view Z_MY_CDS_VIEW as select from some_table {
    key field1,
    field2,
    sum(field3) as total_field3
}
group by field1, field2

2. Exposing CDS Views as OData Services: To integrate CDS views with SAP Fiori apps, they need to be exposed as OData services. This is done using the SAP Gateway, which allows Fiori apps to consume the data via standard web protocols.

3. Integrating with Fiori Apps: Once the OData service is set up, it can be consumed by Fiori apps. Developers configure Fiori tiles and applications to use the OData services, ensuring that the data presented aligns with the business requirements.

4. Testing and Validation: Thorough testing is essential to ensure that the CDS views deliver accurate data and perform well under different scenarios. This includes validating data accuracy, performance, and the user experience in Fiori apps.

Conclusion

Core Data Services (CDS) views are a fundamental component of the SAP Fiori ABAP Programming Model, offering a powerful framework for data modeling and integration. By providing a semantic layer over raw data, CDS views enable developers to create efficient, real-time, and user-centric applications. Their ability to simplify data modeling, optimize performance, and enhance user experience makes them indispensable for modern SAP Fiori development.

Implementing CDS views effectively requires careful planning and execution, from defining the views to integrating them with Fiori apps. Embracing CDS views not only streamlines data management but also ensures that SAP Fiori applications deliver meaningful and actionable insights to users. As organizations continue to evolve and leverage advanced technologies, understanding and utilizing CDS views will remain a key factor in achieving success and driving innovation in the SAP ecosystem.

Salesforce Incident Management: Streamlining Issue Resolution

How the Digital Services Act is Shaping the Future of the SAP Community

The post SAP Fiori ABAP Programming Model – 2 – CDS – Overview first appeared on TECHNICAL GYAN GURU.

I have created a series of questions and answers from my study notes in the hopes that these may assist the deserving candidate who wants to ace the interview for his next project/job. Although you still need to thoroughly comprehend each topic to have a firm grasp of the principles, this quick Q&A may help you review and assess your knowledge.

Q1. SAP Fiori LaunchPad Benefits

Adaptability

Device Assistance

Independent of Platform

Support for Browsers

coherent in character

Combination

Open norm

Record-keeping

First, decide which view (the default view) to load into the app control.

Step 2: Add the view’s object (page) to the app to make the view aware of it.

We return the main view’s object in the createContent method. that is, the page

3. How Do I Make a Control in the User Interface?

The process involves creating an event for a control (such as a button), defining it in the controller, and then adding the control to the page.

Q4. Using the API to switch to a different view?

Answer app.to

Q5. How can I obtain the object’s runtime instance in order to access the control’s object?

The answer is sap.ui.getCore.byId (“”).

6. Explain the SAP UI5 Framework.

A framework for creating responsive web applications is SAP UI5. Performance has nothing to do with responsiveness; responsiveness is the capacity of a program to adjust to any type of device. It provides a consistent user experience on all platforms (various browsers and devices).

A framework is made up of libraries; libraries contain classes, and classes contain methods.

Q7. UI technology evolution

Q8. Explain the SAP UI5’s design-time and run-time components.

Yes, in fact. Typically, a framework is made up of two kinds of libraries, each of which has two components: Design-time The SAP UI5 component includes all of the classes, frameworks, and functionalities needed to build any kind of application from the ground up.

The Fiori application is executed by the SAP UI5 run-time component, which also includes a renderer that converts the application code into a format that is readable by browsers (such as HTML5, CSS, and JS).

Q9. What are the steps involved in creating an application in any programming language?

Bootstrap in UI5 –

1 Initialization – Load required dependencies \script id=”sap-ui-bootstrap” src = “sap-ui-core.js” = “sap.m”; data-sap-ui-libs;With theme “sap_bluecrystal,” data-sap-ui
In the tag of the HTML document, specify class=”sapUiBody” to make the theme active on the page.

2. Declaration – Program Data Variables – Create User Interface Control new libraryName = var var_name.ClassName(sId, sProperties); sId: your UI control's unique ID sProperties: To configure control attributes, use control properties. inside braces with curls.

( ) – curly braces [] – parenthesis { } – bracket

3. The real program logic, also known as orchestration logic, which includes manipulation, IF, loops, calls, and user display control

PlaceAt(“id of control”) for ObjectContro ;

4. Output: Present the user’s output.
5. Tidying Up

Q10. How can the Bootstrap for UI5 framework be loaded so that it can function offline?

Observe the index.html file’s syntax:

The rationale is that all UI5 Framework Libraries are pre-installed on Orion Server, which powers the WebIDE local installation. We define neo-app.json, which serves as an interface between Orion Server ->> Resources (test) to load the framework and use the libraries within.

Q11. How to load the Bootstrap for UI5 framework to work in the Offline Mode?

Reason being: Since the WebIDE local installation runs on Orion Server, which has all UI5 Framework Libraries pre-existing in the Server. To access the libraries in the framework, we define neo-app.json which acts as an interface between Orion Server ->> Resources ( test ) to load the framework.

Q11. Define structure of a Web Application / HTML page?

Every web application that a browser can comprehend is always an HTML page, also known as a static webpage. An HTML page is the typical web application page’s structure.

<html>
                <head>
                                ( * creation of control )
                </head>
                <body>
                                ( * place the control in the body )
                </body>
<html>

12. What is the SAP WEB IDE?

Yes. Developers can construct and extend Fiori Apps using the SAP WebIDE Integrated Development Environment (IDE).

• Developing Fiori Apps is made simpler by employing pre-made templates.
• To expand Fiori Applications, use the Extensibility Pane.
• Numerous choices for deployment.
• permits group repository sharing. Git repository
• can use any device to access it from anywhere. No local footprint; installation must be done locally.

Q13. What is HTML?

HTML stands for Hypertext Markup Language which is created by W3C = World Wide Web Consortium who is responsible for defining HTML tags and versions. All browser vendors like Chrome, IE, Firefox, Safari.

It is used to create static web pages.

HTML is not a programming language. It is based on tags, if we follow the approach, we can create a static webpage using these standard tags. E.g. button, input, datalist, li, ul, h1, table … etc.

Important Points to be noted:

• HTML is not case-sensitive
• Browser directly understand HTML
• User can only see content in browser provided it is kept in body of HTML
• Every HTML element can have ID property. Developer should make sure that ID is always unique.
• Html elements can also have name, class (classification) property, which doesn’t needs to be unique.
• Difference between HTML and HTML5?
  • HTML5 is just the advancement of HTML, it was released in year 2014.
  • HTML5 is labral in nature
    • Even we put something in head of html, it will be visible to user. Ideally we should not do that.4
  • Declaration of DOCTYPE

Older version example <!DOCTYPE html DND_VERSION=“XHTML/4.02” HTMLSCHEMA=“htmlns”>

<!DOCTYPE html> à tells the file that it’s an html page

• For some of the tags in HTML5, we don’t need to put ending tag e.g. img, input
  • New elements introduced to define proper structure of the website like header, footer, article, section etc.
  • Direct support for Audio and Video tags in HTML5, before that plug-in support was needed in browsers

Q14. Difference between HTML5 and SAP UI5?

Q15. Difference between Open UI5 and SAP UI5?

• The most widely used libraries for user consumption are included in Open UI5, which is a subset of SAP UI5.
• While SAP UI5 is a licensed product that is included with SAP Netweaver or SCP (SAP Cloud Platform, formerly known as HCP – HANA Cloud Platform), Open UI5 is available as open source under the Apache 2.0 license.

Q16: In HTML, what is a metatag?

It shows the HTML page’s metadata. (For additional information about attributes, visit www.w3cshools.com.)
Features of a metatag include:
Encoding type: aids the user in determining the appropriate character type
Author: Keyword generated content that appears in a metatag for search engine optimization
Description: An overview of the websites found in search engine

Q17. What do HTML List tags mean?

Data sequences are displayed using list tags.

Two categories of list tags exist:

List not in order: <ul></ul>
List in order: <o></o>

Q18: What elements are at the block level?

The HTML content is correctly structured through the usage of block level components. These components don’t take up any space on the page. Two kinds of elements at the block level:

div stands for division tag.

It begins automatically with a new line.
used to assemble or form a block of components.
span is an inline element.

It doesn’t begin with a new line.
It encloses a preexisting HTML component.

Question19: What is the Document Object Model, or DOM?

The process by which a browser transforms HTML into a tree data structure is called Document Object Model, or DOM. HTML’s runtime structure in a browser.

20 What does HTML table structure mean? Q20.

Q21: What is the <iframe> tag?

<iframe> tag in HTML is used to embed another HTML document.

<iframe href=“(reference of the HTML document)” width=“” height=“”></iframe>

Q22: What is CSS?

Cascading Style Sheet is what CSS stands for. The styling of an HTML element is accomplished by using CSS, which keeps style code and HTML code apart. Three approaches to using CS
1. Inline style is similar to styling at the element level. Overuse of code

Syntax:

                <style>
                                selector : {
                                                prop: value;
                                                prop: value
                                }
                </style>

3. External Style

23: What’s Inline Styling?

All of the elements defined in the tag are styled at the element level or tag level using inline styling. Therefore, it is not possible to apply style to every element if there are several. Then, we employ Internal Style.

Q25 Can you explain responsive web design?

Web design that automatically adjusts to the size of the screen to offer a constant user experience. Without a scroll bar at the page level, the screen adapts itself based on available space on the device.

26 What is the CSS box model, Q26?

The way an element appears on an HTML page with a border and the actual element is called the CSS box model. Padding (property) is the space between the element and the border; margin (pro) is the space between two distinct element boxes.

Q27: In CSS, what is a pseudo class?

Pseudo classes are essentially unique IDs that allow CSS to be applied to items in response to specific user actions or events on the user interface.

choice: pseudo-class� �—CODE

** w3cshools.com has a list of available pseudo classes, such as FOCUS, HOVER, etc.

Question 28: What exactly is JavaScript?

It’s a programming language that the browser can understand. It differs greatly from Java in terms of philosophy, design, and goal.

Case matters in JavaScript
The naming convention that must be used when declaring “functions” and “variables” in JavaScript
The first word should begin with a small letter, followed by a camel cap or the initial letter of the following word in capital letters, for example, Hello World -> helloWorld.

Each and every JS statement should conclude with a semicolon (;)
centered around objects.

Q29: What kinds of JavaScript (JS) are there?

Two varieties of JS exist:

clientele JS: JavaScript code that executes entirely client-side, within a browser. to create online apps that are responsive, such as Angular JS and UIC5.
server-side JS: Server-side JS code is executed. such as Node.JS and XSJS. Server-side programming includes functions like emailing, DB searches, data manipulation, and system status updates.

Q30: What is JavaScript’s (JS) purpose?

Yes. The following uses exist for Java Script:

Verify the information.
Carry out the client’s calculations: Write if, looping, arithmetic, and logical operations in imperative logic.
Examine the circumstances and functioning of the
Speak with the call server
Change the DOM (html)
Runtime CSS changes

Q31. Steps/Techniques to apply JavaScript in the code?

3 ways we can apply JS in the code:

1. Inline JS – code is written at element level
2. Internal JS – code is written at page level inside <script></script> tag.
3. External JS – reference an external file (.js) into your html page,                                           

<script src=“(path of JS file)”></script>

Q32: What are the various JavaScript output functions?

alert(): Show the user Console a popup.log: Print the results to the console document.Write content to take the place of the entire HTML page.innerText: Modify an HTML element Q33’s text. Which pre-defined objects are available in JavaScript?

Two categories of entities:

The term “document” refers to the object of your Document Object Model (DOM), which is the runtime structure of an HTML page. The document object offers numerous methods to access the object of an HTML element or elements, which are represented by reusable methods or classes called APIs, or Application Programming Interfaces.

The single element can be found using document.getElementById (the id of an HTML element is unique).
This is the browser window’s object: document.getElementsByClassName returns a list of all elements by class name; document.getElementsByTagname returns a list of all elements with that tag.

Q34: What is the syntax in JavaScript for creating variables?

Question 35: What is Java Script Object Notation, or JSON?

If an array has to define more than one record, more objects must be added to the array. Java Script Object Notation, or JSON, is the idea behind fusing arrays and objects together.

var myItab = [{“prop”: val, “prop”: val}, {“prop”: val, “prop”: val}, {“prop”: val, “prop”: val}, {“prop”: val, “prop”: val}, {“prop”: val, “prop”: val}, {“prop”: val, “prop”: val}, {“prop”: val, “prop”: val}, {“prop”: val, “prop”: val}]

Q36: What kinds of JavaScript functions are there?

Two categories of JS functions

1. Anonymous functions (nameless functions)

function(argument, argument) { ^                               

2. Named functions (functions that you have defined yourself)

function functionName(argument, argument){ �                                                                                                  �

Crucial: An argument can be supplied to a function.

var = function(){ ….

Q38: Describe jQuery.

A language is not jQuery. It is a short and efficient JavaScript package that helps you avoid writing lengthy JS code. The idea behind it is “write less, do more.”

The most often used lines of code and methods can be included into application code using jQuery, enabling developers to rapidly accomplish their goals with little to no coding.

This library can be used in two ways:

Get the jQuery plugin, add it to your project, and use it locally.
Internet source cited as CDN (Content Delivery Network)
jQuery Library loading is required. ->

The syntax for using a jQuery library, which is an external JS file, is as follows:

Q39. How to Use jQuery Syntax

the action() of $(selector);

$ – instruct the browser that we’ll be using jQuery
Selector: #id, #className, tagname
Action: method, name of the event, on, css(‘prop’,’val’)
$(selector).action(callBackFunction(), parameters);

What is the Document Object Model, or DOM?

The process by which a browser transforms HTML into a tree data structure is called Document Object Model, or DOM. HTML’s runtime structure in a browser.

To access the internet developer toolbar and developer tool, press F12.

What’s Inline Styling?

All of the elements defined in the tag are styled at the element level or tag level using inline styling. Therefore, it is not possible to apply style to every element if there are several. Then, we employ Internal Style.

Could you explain internal styling?

A selector can be used to apply internal styling to a set of items at once.

One of the two ways to utilize a selector is as a unique identification of an element or elements.

#id: using a specific element’s style

.className: This class name categorizes items or groups of elements; to use it, insert the element inside a

tag.

For instance,

“your element”

tagName: each element that hast level. But wrap the element around a tag with a div tag and use class name.

Can you explain responsive web design?

Web design that automatically adjusts to the size of the screen to offer a constant user experience. Without a scroll bar at the page level, the screen adapts itself based on available space on the device.

What is the CSS box model, Q26?

The way an element appears on an HTML page with a border and the actual element is called the CSS box model. Padding (property) is the space between an element and its border; margin (property) is the space between two distinct element boxes.

In CSS, what is a pseudo class?

Pseudo classes are essentially unique IDs that allow CSS to be applied to items in response to specific user actions or events on the user interface.

choice: pseudo-class{ —CODE** list of accessible pseudo

Q30. What is the purpose of JavaScript(JS)?

Ans. JAVA Script is used for following purposes:

1. Validate the input
2. Perform calculations on client side: Write imperative logic – if, looping, arithmetic and logical operations
3. Check conditions and operations
4. Call server
5. Manipulate DOM (html)
6. Change CSS at runtime

(“id of control”);

2. Using View object when we use MVC architecture (XML Views)

                this.getView().byId(“id of control”);
                this keyword represents the object of current control.

In UI5, how can I construct a control?

How to write a control in syntax:

oControlName in var o = new .sId, sProperties as ControlName;

Keep in mind that the control name is usually capitalized at the beginning. A case of pure camels.

sId: The control’s distinct ID.

sProperties: the UI element’s characteristics or attributes. Every property needs to adhere to the syntax below.

{ propname: “prop val”, propname: “prop val” }

How does a SAP UI5 control define its control hierarchy?

Things to keep in mind when using the SAP UI5 hierarchy

The “extends” keyword in JavaScript is used to denote inheritance.

If a specific class’s property or event is not visible, try looking through its parent class.

How Can I Get Change/Display Functionality and Embed a Fragment Straight into the View?

The following is how an ICONTAB FILTER is often implemented:

In SAP UI5, what does a TABSTRIP control mean?

In UI5, a TABSTRIP UI is implemented using ICON TAB BAR

A typical ICONTAB FILTER can be implemented as follows:

Use SAP UI5 to implement TABLE CONTROL

A table is a multi-column list control. It is a part of the sap.m library, and you can see that it “extends” the sap.m.ListBase Class in the SDK when you check sap.m.Table. And it has aggregation as “columns” to enable multi-column user interface.

Q102: Which Control endows a Text Control with properties like colors and icons?

Additionally, develop a formatter function in order to attain the “intuitiveness” in the table column:

CREATE

Similarly,

What does SAPUI5’s Fragments mean?

Reusable UI components called fragments are used to modularize user interfaces in UI5 applications. We are dividing up the UI into fragments utilizing the fragments, much like we do with custom controllers in UI5. These parts can be combined or utilized again by different controllers or views. Therefore, the matching controller of the view in which the fragment is declared defines the logic for Fragment Control components. (To hear an explanation with more examples, watch the video.)

How Can a View’s Fragment Be Declared?

Step 1: To call the pop-up fragment, provide an input field for the F4 help. applying the “valueHelpRequest” method

Thus, while integrating sap.m.Dialog into your fragment, make sure to verify the SDK: the

create

Additionally, when the “Approve” button is clicked, a pop-up message is displayed via the message-box API.

REMEMBER!! Always realize to specify a global variable for the object in order to preserve I/O on the pop-up fragment. This will ensure that the pop-up’s properties are maintained even if user action is taken on it.

.. What is the meaning of a custom control and what does it accomplish?

*** UI Controls / Elements are reusable UI5 components that can be used to customize the UI in many ways.

To accomplish a feature that isn’t included in Standard, you can create your own reusable control by designing it in a different file that serves as a library.

The post 130 SAPUI5, SAP Fiori, HTML, CSS, JavaScript & jQuery, Interview Questions & Answers first appeared on TECHNICAL GYAN GURU.

Data is arranged using an OData service as entities, which are collections of attributes related by associations. Since these components are similar to those in CDS data models, CDS data models are ideal candidates to be exposed as OData services.

Annotation for OData Service Creation
To build an OData service, use the annotation below.

True @OData.publish

This annotation needs to be written above the define View † statement in the header section of a CDS view.

@AbapCatalog.compiler.compare @AbapCatalog.sqlViewName: ‘Z_C_AIRLINE’True for the filter

AbapCatalog.archiveImportant: accurate

choose from ZAPF_I_AIRLINE to define view ZAPF_C_AIRLINE
{ ………… }
Now let’s add this annotation to the CDS view. Please be aware that just one location throughout the CDS data model requires the implementation of this OData annotation. We have established the primary hierarchical point for the entire data model as the ZAPF_C_AIRLINE consumption view. This annotation will therefore be shown in the main consumption display.

When the CDS view is activated and the OData annotation is applied, an OData service will be built. The OData service for the aforementioned Airline CDS view has now been established and activated. However, the service won’t be accessible for use. The corresponding service must be activated in order for the external system or Fiori application to use it.

The following chapter of this series will go over how to activate the OData service that was created in the previous phase.

In the ever-evolving landscape of SAP, the ABAP Programming Model has become a cornerstone for developing robust and scalable applications. Among the various aspects of this model, OData service generation stands out as a crucial component, especially when it comes to creating seamless SAP Fiori applications. This blog post will delve into the process of generating OData services using the ABAP Programming Model, showcasing how you can leverage these services to enhance your SAP Fiori apps.

1. Introduction to ABAP Programming Model and OData Services

The ABAP Programming Model offers a structured approach to developing applications on the SAP platform, focusing on best practices and design principles. Within this model, OData services play a vital role by facilitating the interaction between the SAP backend and SAP Fiori front-end applications. OData (Open Data Protocol) is a standardized protocol that enables CRUD (Create, Read, Update, Delete) operations on data entities, making it ideal for building interactive and dynamic user interfaces.

2. Setting Up Your Development Environment

Before diving into OData service generation, ensure you have the following prerequisites:

• SAP NetWeaver Application Server: A robust platform for running your ABAP code.
• SAP Business Application Studio or SAP Web IDE: For development and testing of your Fiori applications.
• ABAP Development Tools (ADT): An essential set of tools for ABAP development.

3. Creating an ABAP Core Data Services (CDS) View

The first step in generating an OData service is to create a Core Data Services (CDS) view. CDS views are essential for defining and exposing your data models in a structured manner.

1. Open ADT in Eclipse and navigate to your ABAP project.
2. Create a new CDS view: Right-click on your package, select New > Other ABAP Repository Object > Core Data Services > Data Definition.
3. Define your CDS view: Use the following template to get started:abapCopy code@AbapCatalog.sqlViewName: 'ZMY_CDS_VIEW' @AccessControl.authorizationCheck: #CHECK @EndUserText.label: 'My CDS View' define view Z_MY_CDS_VIEW as select from my_table { key field1, field2, field3 } This CDS view selects data from my_table and exposes fields field1, field2, and field3.

4. Exposing the CDS View as an OData Service

With your CDS view in place, the next step is to expose it as an OData service.

1. Create a new OData service: Go to the SAP Gateway Service Builder (transaction code SEGW).
2. Create a new project: Enter a project name and description, then click Create.
3. Add a Data Model: Right-click on the Data Model node and choose Import > DDIC Structure. Select your CDS view from the list.
4. Generate the runtime objects: Right-click on your project and select Generate. This step creates the OData service runtime artifacts.

5. Register and Test the OData Service

Once the OData service is generated, it needs to be registered and tested:

1. Register the service: Use transaction /IWFND/MAINT_SERVICE to add your OData service to the SAP Gateway. Enter your service name, and follow the prompts to register.
2. Test the service: Use transaction /IWFND/GW_CLIENT or a tool like Postman to test your OData service endpoints. Verify that the CRUD operations work as expected.

6. Integrating OData Service with SAP Fiori

With your OData service up and running, you can integrate it into your SAP Fiori application:

1. Create a new Fiori application: Use SAP Business Application Studio or SAP Web IDE to create a new Fiori project.
2. Connect to the OData service: In the Fiori project, configure the OData service as a data source.
3. Develop your UI: Build your Fiori app’s UI using the data exposed by your OData service. Utilize SAPUI5 controls to create interactive and user-friendly interfaces.

7. Conclusion

Generating OData services for SAP Fiori applications using the ABAP Programming Model simplifies the process of data interaction between the backend and the frontend. By following these steps, you can efficiently expose your data models and create dynamic, responsive Fiori applications that enhance user experience.

Embracing the ABAP Programming Model and mastering OData service generation will not only streamline your development process but also ensure that your SAP Fiori applications are powerful and scalable. Happy coding!

The instructions for activating the previously built OData service are listed below.

Determine which OData service has been generated.
Turn on the OData service for the SAP Gateway.
Determine which OData service was created.
To create the OData service, the corresponding CDS view must be activated after applying the OData annotation.

Open the SAP Gateway System and activate the OData service.

The discovery of the OData service’s name does not imply that it is available for use. It needs to be turned on.

Follow these instructions to make the OData service active:

1. Using the SAP GUI, access the SAP Gateway system and navigate to transaction /IWFND/MAINT_SERVICE.

2. Click the Add Service option to add the service for activation once we are in the transaction.

3. Enter the name of the technical service and the system alias on the next screen. OData is the service name for technical services.

Choose the OData services result that was returned, then click Add Selected Services.

5. Select the bundle.

6. To verify if the service is enabled, return and filter the OData service by its name. Consequently, this will also activate and make the OData service available.

7. After that, proceed as normal to test the OData service and verify the entity data, as shown below. Please refer to the OData service testing from SAP Gateway system on the SAPYard website if this step is unclear.

In the realm of SAP Fiori development, the ABAP Programming Model offers a structured approach to building efficient, scalable applications. One of the key components of this model is the generation of OData services, which are critical for enabling seamless data interactions between the SAP backend and the Fiori front end. This blog post explores the steps involved in generating OData services using the ABAP Programming Model, focusing on practical insights and best practices to streamline your development process.

ABAP Programming Model and OData Services

The ABAP Programming Model is designed to align with modern development practices, emphasizing simplicity and efficiency.

The introduction of business object annotations to Composite interface views is necessary since Basic Interface views must also be reused in other applications. We need to add multiple @ObjectModel annotations to the three composite CDS views in order to construct a BOPF business object based on those views.

We need to add the header level annotations in the Airline root view (ZAPF_I_AIRLINE).

Model @ObjectModel.model@ObjectModel.composition Category:#BUSINESS_OBJECTRoot:actual
@ObjectModel.transactionalProcessingAllowed:actual
The object model writes “SCARR” in the ActivePersistence field.Activated: Yes
@ObjectModel.removeActivated: Yes
@ObjectModel.updateActivated: Yes
describe view ZAPF_I_AIRLINE… {…. }

The list of annotations for BOPF Business Objects is shown below.

Let’s add the BOPF BO annotations mentioned above to our airline model.

On activation of the transactional or business object views, the BOPF runtime will generate a business object together with several structures and table types based on the CDS view field structures. The generated BOPF object has the same name as the
root CDS view, in our case, ZAPF_I_AIRLINE.

To enable our existing consumption views for transactional processing via the generated BOPF business object, we must add some of the @ObjectModel annotations on the header level. To the Airline Consumption view (ZAPF_C_AIRLINE), we must add the annotations given as below

...
@ObjectModel.transactionalProcessingDelegated:true
@ObjectModel.compositionRoot:true
@ObjectModel.createEnabled:true
@ObjectModel.updateEnabled:true
@ObjectModel.deleteEnabled:true
...
define view ZAPF_C_AIRLINE
...
{
...
}

We should mark the view as the root view of our hierarchy node structure by introducing @ObjectModel.compositionRoot: true. Additionally, we must enable all transactional operations separately because they are already known from the Interface views. The only new annotation is the @ObjectModel.transactionalProcessingDelegated: true, which indicates that transactional processing is delegated to the transactional runtime of the underlying view. In our case, ZAPF_I_AIRLINE is the business object and view. Moreover, we must also specify the same association type annotations as in the underlying views, from Airline to Flights Info. and vice-versa.

Additionally, we have to add annotations to Flights Info. Consumption view (ZAPF_C_FLIGHTS) and Flight Schedule Consumption view(ZAPF_C_FLI_SCHED), to enable transactional processing delegation.

...
@ObjectModel.transactionalProcessingDelegated:true
@ObjectModel.createEnabled:true
@ObjectModel.updateEnabled:true
@ObjectModel.deleteEnabled:true
...
define view ZAPF_C_FLIGHTS
...
{
...
}

Once all the BOPF BO annotations are added, our Fiori App will look like below.

Let’s insert data with below details in all three views.

The results of the save procedure are shown below.

We had no trouble saving entities into the appropriate table thanks to BOPF’s assistance. Let’s go into more detail about the other functions that BOPF offers in the upcoming chapters.

Select the “Go to the Root Node” link located in the business object editor.

Click the Actions tab and select New.

A dialog box opens, asking us to enter the action’s specifics:

Name: Type the action’s name here; in this example, it’s “Set URL.”

Description: Write a brief description of the action’s goal, such as “Set the URL.”

Implementation Class: We may either insert an existing class that implements the interface /bobf/if_frw_action~execute, or we can just accept the proposal that will result in the production of a global ABAP class. We’ll refer to the

The actions section can be completed with the code below.

A custom button will appear, and when it is clicked, the URL will be changed in accordance with the code snippet. Let’s examine the BOPF determinations in the following chapter.

Conclusion

Actions in the Business Object Processing Framework (BOPF) are essential for enabling interactive and dynamic functionalities within SAP Fiori applications. By leveraging actions, developers can design intuitive user experiences that allow users to perform specific tasks or operations directly within the application. Actions provide a mechanism for executing complex business processes or triggering workflows based on user interactions, thereby enhancing the overall functionality and responsiveness of the application.

Implementing actions effectively in BOPF ensures that your SAP Fiori applications are not only functional but also aligned with user needs and business requirements. It empowers users to interact with the application in meaningful ways, leading to more efficient workflows and a more engaging user experience.
