Top 20 SAP ABAP Developer Interview Questions and Answers

1. What is ABAP?

ABAP stands for Advanced Business Application Programming. It is a programming language used for building applications for SAP's ERP system.

2. What is the difference between classical and interactive reports in ABAP?

Classical reports are simple reports that generate a list using basic ABAP commands. Interactive reports, on the other hand, allow the user to interact with the report and perform actions such as sorting, filtering or deleting data.

3. What is the difference between transparent, pooled, and clustered tables?

Transparent tables hold application data and can be accessed directly using SQL queries. Pooled tables are used to store data that is shared between different applications, while clustered tables store data from multiple transparent tables, which reduces the number of joins required to access that data.

4. What is an internal table?

An internal table is a data structure that can hold multiple rows and columns of data. They are used to store data retrieved from a database table or for intermediate calculations in a program.

5. What is the difference between an append structure and an include structure?

An append structure provides a way to add fields to a standard SAP table without modifying the original structure. An include structure, on the other hand, is a structure that can be included in multiple other structures, making it easier to maintain and reuse code.

6. What is the difference between a function module and a subroutine?

A function module is a self-contained unit of code that performs a specific task and can be called from multiple programs. A subroutine, on the other hand, is a piece of code that performs a specific task and is called from within a single program.

7. What is the difference between a BADI and an enhancement point?

A BADI (Business Add-In) is a point within an SAP application where a custom-developed program can be called to modify the application's behavior. An enhancement point is a predefined point within an SAP program where custom code can be added to extend the program's functionality.

8. What is the difference between an ALV report and a classical report?

ALV (ABAP List Viewer) reports provide a more user-friendly interface to display data to end-users in a structured and interactive way. Classical reports generate a simple list that can be viewed in a basic GUI.

9. What is a Dynpro and which components are included in it?

A Dynpro is short for Dynamic Program. It is a screen that is used to interact with the user in an SAP application. Components included in it are the screen layout, screen flow logic, and screen elements.

10. What is the difference between an implicit and an explicit enhancement?

An implicit enhancement is a predefined point within an SAP program where custom code can be added. Explicit enhancements are defined by the programmer and are used to add functionality to specific areas of a program.

11. What is an ALV grid?

An ALV grid is a tool used to display data from an internal table in an interactive grid format. It provides features such as sorting, filtering, and editing data directly on the grid.

12. What is an ABAP/4 query?

An ABAP/4 query is a tool used to create custom reports by selecting data from SAP database tables. It allows users to define their own selection criteria and grouping criteria.

13. What is the difference between GET and SET parameters in ABAP?

GET parameters retrieve data from the user interface, while SET parameters set values in the user interface. SET parameters allow for data to be passed between different screens in an SAP application.

14. What is the difference between a smart form and a SAPscript?

Smart Forms are a more advanced version of SAPscript, allowing for more flexibility and features such as dynamic tables and graphics. SAPscript is an older tool used for creating and printing forms in SAP systems.

15. What are the different types of SAP memory?

There are three types of memory in SAP: ABAP memory, export memory, and shared memory. ABAP memory is used to store data for a single program, export memory is used to store data for multiple programs, and shared memory is used for data shared between processes.

16. What is a lock object?

A lock object is an SAP data structure used to control access to specific data in SAP systems. It prevents multiple users from changing the same data simultaneously.

17. What is an IDOC?

IDOC (Intermediate Document) is a data format used to exchange information between different SAP systems or between SAP systems and external systems. It allows for a standardized way of communication and data exchange.

18. What is a BDC program?

A BDC (Batch Data Communication) program is used to automate the process of data entry into an SAP system. It allows for the recording of a user's input and the automatic processing of multiple inputs in a batch format.

19. What is an RFC?

An RFC (Remote Function Call) is a mechanism used to call SAP functions from external systems or from within an SAP system. It allows for remote execution of functions in a different system, providing a way for data to be exchanged between systems.

20. What is an ABAP debugger?

The ABAP debugger is a tool used to find and fix errors in an SAP program. It allows developers to execute a program line-by-line and view the data in real-time, helping to identify any issues in the program logic or data.
