Basic SAP ABAP Interview Questions that asked to Beginners

Q1. What do you understand about SAP ABAP?

A. SAP Advanced Business Application Programming can be considered a high-level programming language which has been developed for building applications within the SAP ecosystem and it helps in creating programs that interact directly with the SAP database and along with that they can even run on SAP NetWeaver platform.

ABAP is mainly used for:

• Creating custom reports

• Developing data interfaces

• Designing forms and documents

• Enhancing standard SAP functionality

• Developing business applications

Q2. What do you mean by SAP ABAP Data Dictionary?

A. You can think of ABAP Data Dictionary (DDIC) as a central repository where metadata which is in relation to database objects is stored and it helps in ensuring the integrity and the consistency of the data across the entire SAP system. It defines and manages the database tables, views, domains, data elements, lock objects and search helps.

Q3. What are Internal Tables in SAP ABAP?

A. Internal tables are temporary data structures used to store and manipulate multiple records during program execution. They exist in memory and are not stored in the database.

• Sorting and filtering data

• Performing calculations

• Temporary data storage

Types of internal tables include:

• Standard Table

• Sorted Table

• Hashed Table

Q4. What do you know about the Transparent Table in SAP?

A. A transparent table is the one that has a direct relationship with a database table.

You can also tell about the nature of the data that is stored in these tables like the customer records and the transaction information.

Q5. Can you differentiate between Structure and Table?

A. A group of fields that are used in programs and do not store data physically in the database is called a Structure while table in contrast stores actual data such as the real business data and has technical settings such as keys and buffering.

Q7. Tell us something about the SELECT statement in ABAP?

A. You can easily retrieve data from the database tables using the SELECT statement. Example:

SELECT * FROM mara INTO TABLE it_mara.

This statement fetches data from the MARA table and stores it in an internal table.

Efficient use of SELECT statements is critical for program performance.

Q8. What is Modularization in ABAP?

A. Modularization refers to dividing a program into smaller reusable components. Common modularization techniques include:

• Subroutine

• Function Modules

• Methods

• Includes

The code readability and maintainability is drastically improved due to Modular programming.

It is a powerful reporting tool that allows users to display data in a structured format.

Features include:

• Sorting

• Filtering

• Exporting to Excel

• Interactive data display

Q12. What is BDC in SAP ABAP?

A. BDC stands for Batch Data Communication. It is used for transferring large amounts of data into SAP systems. Two main BDC methods:

• Call Transaction Method

• Session Method

BDC is commonly used during data migration projects.

Q13. Differentiate between Open SQL and Native SQL?

A. Open SQL is independent of the database and can work with multiple databases supported by SAP and highly preferred over Native SQL which is database specific and makes use of the syntax of the underlying database.

Q14. What is a Transport Request in SAP?

A. A Transport Request is used to move development objects between SAP systems such as:

• Development

• Quality

• Production

Transport requests ensure that changes made in development are properly deployed across the SAP landscape.

Q15. What is RFC in SAP?

A. Remote Function Call or just RFC helps in allowing communication between SAP systems or between SAP and external applications. RFC is commonly used for integration of systems, exchange of data and remote execution of function modules.

Q16. What is a BAPI?

A. Business Application Programming Interface or simply BAPI is a standardized interface which is essential in performing business operations within SAP systems and allows the secure interaction of the external systems with SAP applications.

This approach helps maintain system stability during upgrades.

Q19. What do you understand about ABAP Objects?

A. ABAP Objects is the object-oriented extension of ABAP. It supports OOP concepts such as:

• Encapsulation

• Inheritance

• Polymorphism

• Interfaces

Using OOP improves code reusability and maintainability.

Q20. What is a CDS View?

A. CDS (Core Data Services) views are advanced data modeling objects used in modern SAP development. Advantages of CDS views:

• Better performance

• Code pushdown to database

• Built-in annotations

• Integration with SAP Fiori

• CDS views are heavily used in SAP ABAP on HANA development.

If you want to master modern SAP development technologies, you can learn them through an SAP ABAP on HANA Course online offered by Srijan Institute.

Q21. What is RAP in SAP?

A. RAP stands for RESTful ABAP Programming Model. It is a modern programming model used to develop:

• Cloud applications

• API services

• SAP Fiori applications
