Top C_S4HDEV1909 – SAP Certified Development Associate Interview Questions
1. What programming language does SAP use?
The ABAP Objects programming language, which is developed by SAP for the development of business applications in the SAP environment, allows for object-oriented programming.
2. What is SAP NetWeaver used for?
The SAP NetWeaver is the foundation of all SAP solutions and can be configured or customized to meet specific business requirements. This SAP environment contains many components that are used by organizations in solving specific problems or introducing or managing specific features and functions.
3. What is the difference between SAP ERP and SAP NetWeaver?
First of all, while Netweaver is a platform, ERP is an application. Moreover, all the applications need to be installed over a platform. Further NetWeaver is very generic, whereas the application differs. ERP, BW, EP, CRM are platforms and need to be installed in Netweaver.
4. Are SAP NetWeaver and basis the same?
SAP Basis is a set of functions and tools that form the foundation of SAP’s Web application server, SAP NetWeaver. The original version of Basis, released in 1998, took on the moniker Application Server because it provided the foundation for many applications. The initial release offered built-in Web and Java capabilities. The Web Application Server evolved into SAP NetWeaver by adding new technologies.
5. What are the SAP NetWeaver components?
- Internet Communication Manager (ICM) – SAP NetWeaver
- SAP Web Dispatcher
- Gateway
- Monitor and administer the SAP Message Server
- Standalone Program SAProuter
- Standalone Enqueue Server
- SAP Start Service
- Task handler
6. How would you define the syntax ABAP?
The syntax of the ABAP programming language consists of statements and comments. Keywords begin each statement, and a statement can contain operands or additions. The statement is always concluded with a period.
7. Could you name a few keywords in SAP ABAP?
- Calling Keywords.
- Controlling Keywords.
- Declarative Keywords.
- Definition Keywords.
- Database Keywords.
- Event Keywords.
- Operational Keywords.
8. What is meant by expression-based language?
In an expression-oriented programming language, nearly every construction is an expression and thus yields a value. There are some exceptions—macro definitions, preprocessor commands, and declarations—but these are treated as statements.
10. Can you differentiate between ABAP and SQL?
The Native SQL statements that cannot be executed within an ABAP program are not expressed in the ABAP syntax. Rather, statements exist for isolating program sections in which Native SQL statements can be listed.
11. What makes Open SQL different from Native SQL?
Open SQL statements are those SQL statements we use in ABAP whose implementation is independent of the underlying database. While the Native SQL statements are dependent on the particular DBMS and work only with it.
12. How can you consume a core data services CDS view?
You can preview the CDS view directly within the Eclipse editor by right-clicking on the created view, selecting “Open With,” and then selecting “Data Preview” from the submenu.
13. Could you explain why CDS views are used?
The CDS view can represent a projection onto a Dictionary table or a Dictionary view, and it can define a structure for an SQL view. However, SQL views and CDS entities share the same namespace, so you must assign different names for an SQL view and for the entity.
14. What do you understand by the term in-app extensibility in SAP?
SAP in-app extensibility allows you to tailor SAP software for specific purposes. This flexibility lets you customize the way your SAP application looks and works, create new fields and logic, change the data model, and more.
15. Could you elaborate on the purpose of SCMON?
As the name suggests, the ABAP Call Monitor (transaction SCMON) is meant to monitor the execution (usage) of ABAP code (function modules, method calls, etc.) in your production system.
16. Which programming language does ABAP RESTful application programming model Rap support?
ABAP, the programming language for business applications from SAP, has been aligned and extended to support the development of the ABAP RESTful Programming Model. Together with Core Data Services, CDS, ABAP code is generated automatically by the SAP Web IDE. The application developer uses typed APIs for standard implementation tasks and benefits from auto-completion, element information, and static code checks
17. Could you elaborate on the ABAP RESTful Application Programming model?
The ABAP RESTful Application Programming Model (short: RAP) is the evolutionary successor to the ABAP Programming Model for SAP Fiori. It offers developers an efficient way to build enterprise-ready, SAP HANA-optimized, OData-based Fiori UI services and Web APIs in the cloud as well as on-premise.
18. What does the ABAP RAP model defines?
The ABAP RESTful Application Programming Model (RAP) defines an application programming model for developing services that are cloud-ready, future-proof, and easy to extend. Based on standards such as OData, it provides a unified architecture for the development of enterprise services on the SAP Cloud Platform and in on-premise environments.
19. Can you differentiate between REST API and SOAP?
REST and SOAP are different in many ways. First of all, SOAP requires a formal contract to be implemented whereas REST doesn’t need any contract to be implemented it just follows the convention. REST uses a uniform interface for communication.
20. What all operations can we perform using CDS with the help of BOPF?
- Firstly, creating tables
- Creating a CDS View with BOPF BO Enabled and with annotations with oData Publish
- Also, testing the BO
- Registering the oData and testing in gateway client
- Then, creating a list report & object page Fiori app
- Testing the basic CRUD on the Fiori app
- Last but least, adding a custom action to the BO
21. What do you know about the SAP Fiori elements?
Both SAP Fiori elements and SAP Fiori tools, which are integrated into the SAP Web IDE, help with frontend app development. They speed up frontend development and improve consistency by using predefined floorplan templates and guided project setup that automatically fills in many default settings.
22. Could you explain the use of Fiori in SAP?
The SAP Fiori design system enables you to create business apps with a consumer-grade user experience. It brings simplicity, role-based access, and a consistent look and feels to the enterprise software experience. The design system is meant for developers, user experience designers, and visual designers.
23. How would you describe the Gateway system in SAP Fiori?
SAP NetWeaver Gateway is a technology that provides integration between the SAP Business Suite and target clients, platforms, and programming frameworks. It allows you to use various development tools to create OData services for different platform clients, including browsers, smartphones, and tablets.
24. What is the SAP gateway used for?
SAP Gateway is an integral part of SAP NetWeaver. It lets you connect devices, environments, and platforms to SAP systems using the Open Data Protocol (OData). This means that you can use any programming language and model to connect to SAP applications and non-SAP applications.
25. What is meant by the term custom code migration in SAP?
The Custom Code Migration Worklist is an efficient tool to identify the Simplification Items relevant to your custom code. It integrates information from both, the Simplification Database and the Customs Code Analyzer. Custom Code Migration Worklist helps you analyze your custom code and identify usages of SAP objects identified as relevant.
26. What are the functions of the ABAP Managed Database Procedures AMDP framework?
The ABAP Managed Database Procedures (AMDP) framework offers a way to implement database procedures in the SAP HANA database using SQLScript. The classical approach embeds SQL statements or a database procedure called in ABAP code using the “Native SQL” interface. You thereby duplicate code in two languages and create a maintenance burden for yourself
27. Can we directly call a database procedure inside the AMDP method?
Database Procedure HANA database procedure is a set of SQL statements that are grouped together to perform some specific database operation that can be called by different applications. It can be created and executed with the same procedure in the SAP HANA database through SAP HANA Studio.
28. How would you define table functions with CDS?
As with all CDS entities, a CDS table function entity can be exposed as a remote-enabled function module and consumed by external tools. You can also retrieve data from each individual parameter entity and determine the name of the CDS table function.
29. What does the side-by-side extensibility option mean?
Side-by-side extensibility is the term for building custom applications and developing code for, or alongside, SAP Customer Experience as an integrated part of the offering. You can configure most objects in the SAP Customer Experience system with side-by-side extensibility tools, which are available to you based on the type of tenancies that you have.
30. What do you know about the SAP Cloud Platform connectivity?
SAP Cloud Platform connectivity service is a cloud service providing the API and runtime to build secure connections between SAP Cloud Platform applications and services hosted in the cloud or on-premise. You can configure TCP, HTTP, HTTPS, and other transport protocols from SAP Cloud Platform applications to remote services in your backend systems.
