SAP ABAP Basic Interview Questions

Here is a list of basic interview questions and answers for SAP ABAP: 

1. What is SAP ABAP and how is it utilized within SAP systems?

SAP ABAP (Advanced Business Application Programming) is a high-level programming language developed by SAP. It is used for building applications within the SAP ecosystem, such as custom reports, interfaces, forms, and enhancements. ABAP runs on the SAP NetWeaver platform and interacts with databases and user interfaces.

2. Differentiate between a transparent table and a pooled table in SAP.

A transparent table has a one-to-one relationship with a physical table in the database. Each field corresponds to a database column. A pooled table, on the other hand, stores data for multiple logical tables in a single physical table. Transparent tables are used for application data, while pooled tables are mostly used for system data.

3. Explain the concept of Data Dictionary in ABAP.

The ABAP Data Dictionary (SE11) is a central repository for data definitions. It stores metadata like tables, views, domains, data elements, search helps, and lock objects. These definitions control how data is stored, validated, and accessed across programs in SAP.

4. What are internal tables, and how are they used in ABAP?

Internal tables are temporary data structures used to store and process multiple records during program execution. They are used for data manipulation, transformations, and storing query results. Internal tables do not exist in the database and are held in memory.

SAP ABAP Interview Questions for Freshers

Here are some common SAP ABAP interview questions with answers for freshers: 

5. What are Smart Forms in SAP ABAP, and how do they differ from SAP Scripts?

Smart Forms are used for designing print layouts. Unlike SAP Scripts, they offer a graphical interface, don’t require scripting, and support dynamic table rendering. They also support output in PDF format and are easier to maintain.

6. Explain the difference between structure and table in the Data Dictionary.

A structure is a grouping of fields without data storage; it’s used in programs or as part of a table. A table stores actual data and can have keys and technical settings like buffering.

7. What is the significance of the ‘SE38’ and ‘SE80’ transactions in ABAP development?

SE38 is used to create and execute ABAP programs. SE80, the Object Navigator, provides a complete development environment including access to programs, classes, function modules, and more.

8. How does the ‘SELECT’ statement function in ABAP?

SELECT is used to retrieve data from database tables. It supports conditions, sorting, joins, and aggregates. It’s optimized when used with key fields and indices.

9. What are the different types of reports in SAP ABAP?

There are three main types: Classical, Interactive, and ALV (ABAP List Viewer) reports. Each serves different UI needs, with ALV offering more flexibility and features like sorting and filtering.

SAP ABAP Interview Questions for Experienced

If you are an experienced professional, here are some commonly asked SAP ABAP interview questions for you: 

10. Explain the Enhancement Framework in SAP ABAP.

The Enhancement Framework provides methods to extend standard SAP applications without modifying original code. It includes implicit and explicit enhancements, BADI, and enhancement spots.

11. What are OSS notes in SAP, and how are they implemented?

OSS Notes are SAP’s published corrections and updates. They are applied via transaction SNOTE, which fetches and installs fixes directly into the system.

12. Discuss the differences between BAPI and RFC in SAP ABAP.

BAPIs are standardized function modules for business object interactions. RFCs are remote-enabled function modules. All BAPIs are RFCs, but not all RFCs are BAPIs.

13. How do you optimize the performance of an ABAP program?

“I use tools like ST05 and SAT for trace analysis, minimize nested SELECTs, prefer HASHED or SORTED tables, and reduce database round-trips.”

14. What is the role of ‘SAP NetWeaver’ in ABAP development?

SAP NetWeaver is the technical foundation for SAP applications. It supports ABAP and Java development, integrates different systems, and provides services like workflow, portal, and data exchange.

Technical SAP ABAP Interview Questions

Let’s go through the technical ABAP interview questions and answers.

15. What are field symbols and data references in ABAP?

Field symbols are placeholders or aliases for memory areas. They are similar to pointers in other languages and are declared using FIELD-SYMBOLS. Data references point to data objects and are declared using DATA … TYPE REF TO.

16. Explain the difference between ‘CALL TRANSACTION’ and ‘SESSION’ methods in BDC.

CALL TRANSACTION runs the transaction online and is faster but harder to troubleshoot. The Session method creates a batch input session using BDC_OPEN_GROUP, which can be monitored and debugged via SM35.

17. How do you implement SAP LUW (Logical Unit of Work) in ABAP?

SAP LUW manages database changes until a COMMIT WORK is issued. It can span multiple dialog steps using function modules marked as “update” or by using subroutines with PERFORM ON COMMIT.

SAP ABAP Scenario Based Interview Questions

These are some frequently asked SAP ABAP scenario based interview questions and answers: 

18. Given a performance issue in a report fetching large volumes of data, how would you approach optimization?

“I would analyze it using ST05 or SAT, reduce nested loops, use proper indexing, switch to parallel processing or pushdown via CDS or AMDP if needed.”

19. If a standard SAP function module does not meet client requirements, what steps would you take?

“I’d first check for available BAPIs, BADIs, or user exits. If none fit, I’d create a wrapper or custom FM without modifying the standard code.”

20. Describe how you would handle data migration from a legacy system to SAP using ABAP.

“I’d use LSMW or BDC for structured loads. For large datasets, I’d prefer direct input methods or IDocs, validating data before upload.”

SAP ABAP Developer Interview Questions

Let’s cover the important SAP ABAP developer interview questions and answers. 

21. What are the best practices for modularization in ABAP?

Use function modules, methods, and subroutines to split logic. Avoid duplicate code and follow naming conventions for clarity and reuse.

22. How do you manage version control and transport requests in an SAP landscape?

“I work with transport requests in SE10 and STMS, document each change, and coordinate releases with the BASIS team.”

23. Discuss the use and advantages of ABAP Object-Oriented Programming.

OOP in ABAP promotes cleaner code through encapsulation and inheritance. It simplifies testing, reuse, and maintenance across projects.

Note: SAP ABAP developer interview questions often focus on real-world problem-solving, performance tuning, modularization techniques, and debugging.
