The SAP Netweaver Gateway and OData Tutorials’ five earlier sections included practical exercises along with some technical insights.Those lessons would be helpful and sufficient for ABAPers, but in order to communicate what we know, there are various terms and jargons we need be aware of.We are also able to take part in the constructive conversations and debates. The frequently asked questions about the following subjects may aid in your comprehension of the terminology that have already been covered in previous sections.
Some of you may think that this article ought to be the series’ debut piece. My friend, you are correct. This subject was included in every introduction.However, at SAPYard, we start by giving you the foundations and then we show you the real stuff—hands-on SAP—before beating around the bush to add further clarity.
OData was created by who?
Microsoft, 2007.
Who were the key figures in the OData standardization process?
Answer: Citrix, Progressive Software, WSO2, IBM, Microsoft, and SAP.
Is OData currently managed by Microsoft or by another entity?
The Oasis Organization (Organization for the Advancement of Structured Information Standards) currently oversees OData.
What is OData’s advantage?
Answers:
- • OData decouples data provisioning from
- UI designers by acting as a bridge between SAP developers and UI designers (non-SAP developers);
- • It supports multichannel access to SAP data as it is supported by multiple platforms;
- • It is lightweight and built on the HTTP protocol, allowing database-like access to data via the web.
- Because OData communications are self-descriptive, any non-SAP developer can comprehend their content without the need for additional
- The URI (Uniform Resource Identifier) is the standard address representation or resource that all players can simply access.
- OData supports common industry-wide formats like the JSON and Atom Pub formats, which are based on XML. This facilitates learning, comprehension, connection, and consumption.
When did SAP Netweaver Gateway have its start?
May 2011, to be exact.
SAP Netweaver Gateway: What is it?
In response, this technology offers a straightforward method of connecting to SAP Software from many platforms, contexts, and devices using widely accepted market and industry standards. Put another way, it’s a platform that, independent of existing SAP knowledge, enables access to SAP Applications using any model or programming language.
SAP Netweaver Gateway is a gateway or gate that allows the outside world to peek into SAP, as we have stated many times in all of our prior writings. Without any prior SAP experience, front-end developers of non-SAP systems can create apps that can use data from SAP with the aid of SAP Netweaver Gateway.
What distinguishes OData from OData Services?
The web protocol OData is used to retrieve and update data. It is simpler to use and comprehend because it is based on widely accepted industry standards like XML and JSON. SAP Applications and Data are accessible through OData Service, which also implements the OData protocol and exposes endpoints.
What advantages does SAP Netweaver Gateway offer?
Answer: Using OData Services, SAP Netweaver Gateway enables the provision of a single solution to numerous customers. Thus, one can avoid point-to-point solutions, which can be costly and difficult, and opt instead for SAP Netweaver Gateway and OData Service single point solutions.
- Any device or technology can serve as the frontend; hence, backend developers (ABAPers) do not need to worry about what frontend technology or who will use their OData services. Thus, the responsibilities of front-end and back-end developers may be divided.
- Meets all the end user expectations and business application needs of contemporary business applications.
- SAP Netweaver Gateway installation is easy and non-disruptive (zero downtime).
What is SAP Netweaver Gateway’s architecture?
The architecture of SAP Netweaver Gateway is composed of three layers, same like that of SAP.
SAP Netweaver Gateway Tier (Heart + Middle Man) • SAP Business Suit Tier (Backend) • SAP Consumer Tier (Frontend)
SAP Business Suite Tier 1
This is where the business logic and application data are located.
- It comprises of Service Provider Implementation based on the Add-on IW_BEP (Business Enablement & Event Provisioning) and Development Tools (Service Builder, i.e. T-code SEGW).
- In turn, Service Provider Implementation connects to the SAP Business Suit system and can connect to different SAP Interfaces, including RFCs, BAPIs, BW, HANA, and BOL.
SAP Netweaver Gateway is Tier 2
. Tier: • Supports the majority of Netweaver Gateway features and parts, such as the core component • Serves as a conduit between the Business Suit Layer and the Consumer Layer • Offers instruments for building and enhancing services
Comprising Runtime and Metadata Components, the Service Registry maintains the connection between the OData Service and the service’s real implementation.
One component of metadata is managed, which details the OData models that are exposed as documents in OData Services and OData Service metadata documents.
OData Library: ₧ Contains metadata unique to SAP that uses SAP Business data that is obtained from SAP Data Dictionary.
Tier 3: Consumer Tier consists of UI-centric clients, such as desktop, tablet, mobile, and web apps.
- Capable of developing applications that may swiftly and readily consume services; • SAP Netweaver Gateway service consumption actually occurs at the consumer layer
- The Consumer Layer consists of two different kinds of components.
i) Consumer SAP Netweaver Gateway
ii) Standard environments such as Eclipse or Microsoft Visual Studio are known as Integrated Development Environments (IDEs).
How does the web browser and SAP Netweaver Application Server communicate?
Answer: Using Internet Communication Manager (ICM).
TCP/IP (Transmission Control Protocol/Internet Protocol) is contained in ICM.
Manager of Internet Communications
This is one of the few entirely theoretical articles on SAPYard.Even if we place a greater emphasis on practical technical knowledge, we occasionally need to be able to communicate our technical ideas clearly.We are hoping that this essay would assist us in making our technical knowledge more clear.
In the following section of our SAP Netweaver Gateway and OData series, we’ll demonstrate how to leverage the SAP OData Services that we created in earlier sections in our SAPUI5 applications. Please review your concepts and re-train yourself on your SAP system until then. Not from PPTs or PDFs, but from actual SAP systems, is how Team SAPYard prefers to upload pictures.
