German is the language of the SAP Fiori Launchpad. How can I translate it to English?

Review SAP Fiori Tutorial Part III: Three Flow Charts to get the idea of improving the standard Fiori apps. As an example, let’s say you work as a developer in the UK and are unexpectedly given a project that involves non-English speaking nations like Germany, France, Portugal, etc. You ask yourself, what’s the big deal?You could manage it because ABAP is a common language.

As a developer for Fiori, your first job is to figure out why users in the UK are seeing the Fiori Launchpad in German.

You access the client’s Citrix/VPN and notice the German log-on below.

You make a quick guess: it’s possible that German, DE-Deutsch, is the GUI Logon Pad’s default language. As a result, German appears in the Fiori Launchpad as well.

Let’s examine the SAP Logon Pad. You’re correct. Yes, DE (German) is the default language on the Logon Pad.

You continue to do this. By taking the actions listed below, you can set EN (English) as the default language.

It would request the confirmation listed below if you clicked OK. Press OK once again.

Start the Logon Pad again now.

That you finished the case in under two minutes makes you proud. Let’s take another look at the Fiori Launchpad. Since we have changed the default language in the SAP Logon Pad to EN, we anticipate that the language will also change to EN.

Whoops! It’s still in German on the Fiori Log On Pad.

The fiori launchpad and SAP Log On Pad are unrelated, we have learned. See Also: SAP Fiori Tutorial, Section I: Installation, Configuration, and System Check. you now acknowledge the gravity of the situation. After much searching, you eventually arrive at www.technicalgyanguru.com and discover this post.

The Internet Explorer (or Firefox/Chrome, etc.) default language determines the language that the Fiori Launch Pad displays by default.

The three steps listed below must be followed in order to modify Internet Explorer’s default language:

In Internet Explorer, click Tools.

2. Select the General Tab, then click Languages under Internet Options.

3. The German language would be displayed as the first choice. Simply use the arrows or the move up and down buttons to bring English—which isn’t the initial option—to the top.

Click OK, OK, to restart the Fiori Launch Pad’s internet browser.

The sorcery was successful. The Fiori Launch Pad is now available in your native tongue. Fiori, which translates to “flower” in Italian, meaning “have fun.”

Thus…How Do You Feel?

We would now like to speak with you.

What are your thoughts on this matter?You will undoubtedly run into a language barrier if you ever work on an international project whose execution is taking place across continents.We previously encountered translation problems with Adobe, SAPScripts, SmartForms, and ABAP reports. The Fiori Apps are now in the spotlight.

My Inbox – Completed Purchase Orders

What should you take into account when creating a Fiori app?
Searching the Fiori Library, which is the Fiori Apps equivalent of the Bible or warehouse, is the first task.

I must first verify it in the Fiori library in order to fulfill my requirement, which is to develop the Purchase Order Approval App. If I get it, I’m lucky.

2. Verify that the Release Strategy functions in the Backend Server as intended.

Look it up on the Fiori Library app store.

Locate the SAPUI5 Application in Configuration and note its technical name: CA_FIORI_INBOX

Verify the system version for which you need to construct the app under Implement Information.

Have you played Fiori From Space Level?

Let’s examine what has to be done on these backend and front end servers.

Activate the Sicf service by going to the front end server: ca_fiori_inbox->sap->bc->ui5_ui5 and sicf->default_host->sapturn on

4. In the setup, observe the OData Service

That is all. We possess the names of the frontend and backend services. Proceed to the front end server and utilize the Tcode: /IWFND/MAINT_SERVICE to enable the odata services. When enabling the services, kindly check the System Aliases.

Verify your system’s alias. IW_PGW should be the system alias (extremely crucial).

5. An RFC connection ought to be used to connect the gateway server and the back-end server.
6. Back-end Server: My Workflow is now required to take center stage.

Like any other approval procedure, PO Approval depends on the workflow being operational. Nothing will function without it, so don’t bother with the app.

Now let’s experiment with workflow!

SAP Netweaver -> Content -> Workflow Settings -> Gateway Service Enablement ->Task Filter Activation->Deactivation

SAP Netweaver -> Gateway Service Enablement -> Content -> Workflow Configuration -> Preserve Task Names and Choices

To define the decisions, i.e., the approve and reject buttons, click Decision Keys.

Gateway Server: Set up your gateway system’s workflow scenario.

Choose Task Gateway Service->Scenario Definition under Gateway Service Enablement -> Content in SAP NetWeaver.

Choose an entry and give the customer a role.

Select a Task to Assign to SAP System Alias under Task Definitions.

Front end server approvals

Go to the PFCG, make a Zrole, and select the default authorization.

ID for the program: R3TR
Type of object: IWSG Services: as displayed below: and duplicate.All of these Odata Services ought to be available to the user.

9 Attach Catalog to the Role in PFCG

The standard catalogue must to be accessible to the management as well. Check out the Fiori Library’s regular catalogue role.

Workflow, services, and roles are all operational, as are the frontend and backend servers.

Please make sure the following are set up for Fiori Launchpad.

Find the standard catalog at the Fiori Library.

11 Find the Catalogue name at the Frontend Server using Tcode /n/UI2/FLPD_CUST.

Take notice of every parameter that the standard has already included in the Tiles!

To learn more about Groups, Catalogs, and Tiles, please read through the SAP Fiori Implementation Exercise from beginning to end.

Fiori Launchpad: /UI2/FLP – Designer for Fiori Launchpad

Select Plus Button

Group Home will now have your app launcher added to it. Press the Pencil button.

Select My Inbox to get started. All of the settings and configurations are finished. The purchase order is ready for approval using the My Inbox App. POs in their queues would be visible to managers who have the appropriate roles.

The technical procedures for handling workflow, configuring services, and activating them are finished. However, please read the additional instructions below if you wish to enhance the beauty of your flower (fiori) even further.

While not necessary, these are nonetheless nice to haves. After all, you and other people ought to vary in some way.

13. Theme Designer: To customize your application

Make a call from the frontend server to Tcode /ui5/theme designer.You will see this screen after logging in.

Click SAP_Bluecrystal twice. Paste the Fiori Launchpad URL into the URL to Application field. Give the application a name, then select Add.

You can add the backdrop color and background photos in the right panel.

when the embellishment and personalization are completed. Select Theme, Save, and Build.

Save

The new Theme would be connected to our Fiori App.Navigate to tcode/n/ui5/ theme_tool on the front end server, then select Info.

Look it over!

I believe this post will be useful to you as you set up the Fiori My Inbox app. It should also be possible for you to modify the Fiori Apps’ theme. Feel free to contact me if you run across any problems. I always try to respond to all of the questions that are posed to me.

We had to create a report using splitter containers and a ALV tree structure per a client request. Although handling the combination of these two may seem challenging, it is actually rather simple. We quickly constructed a prototype, and it was flawless.

The basic programming skeleton of the prototype described below can be improved in a number of ways, but it should not change. We discovered certain hotly debated subjects online as we developed, and I’ve tried to hone in on them and address them in this piece.

Goal

This article’s goal is to clarify the usage of the TREE MODEL (TREE_STRUCTURE) and SPLITTER CONTAINER in OOPs ABAP report generation that integrates standard events.

The second, and more significant goal, is to permanently dispel our phobia of using Splitter Containers and Tree Models.

Range

• This article addresses the following typical issues that developers run into:
• When divided into many sub-containers, the custom container can be used to fill the entire screen.
• Registering custom events using the tree model’s standard events
• Customize splitter container widths.

Overview

The report with two containers in the list screen is displayed using the code that follows. The tree model is intended to be contained in the left panel container, while the contents of the left panel document will be displayed in the right container in response to a double click. This example shows how to design a tree structure using sales orders and sales contracts as the antecedent documents. Certain selection screen criteria can be applied to these sales orders in order to choose them. When the leaf node is clicked, the system will show the sales order data in the appropriate container in an ALV format (fig. 1).

Change the design, but feel free to copy or refer to the included code. I would prefer to advise using the local class to help construct the complete report, or at the very least, using some modularization techniques. I utilized several PBO modules, which is strongly discouraged for any real-time object.

There are numerous different methods for creating tree topologies. There are a ton of documents available online. I chose the most straightforward method (the class name is, ironically, “cl_simple_tree_model”).Splitter containers have been extensively studied, although they are rarely utilized unless there are very particular needs.But all this claim is “Old wine in a new bottle,” that is all. I hope this eliminates our reluctance to use tree models and splitter containers.

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:

Getting the Best Salesforce Partner: A Tutorial for Business Growth

The post “A Strategic View of SAP Fiori: Insights from a Space Level Perspective” 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

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.

The post SAP Fiori ABAP Programming Model – 2 – CDS – Overview 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.
