Answer: The Enhancement Framework allows customizing SAP standard programs without modifying original code. Types:
- User Exits
- BADIs (Business Add-Ins)
- Enhancement Spots
10. Difference Between Function Module and Subroutine
| Feature | Function Module | Subroutine |

- Improve performance with push-down processing
- Are defined using SQL-based DDL (Data Definition Language)
12. What is an RFC in SAP ABAP?
Answer: RFC (Remote Function Call) enables communication between SAP systems or between SAP and non-SAP systems. Types:
- Synchronous RFC (sRFC)
- Asynchronous RFC (aRFC)
- Transactional RFC (tRFC)
13. How Does SAP HANA Impact ABAP Development?
Answer: SAP HANA introduces:
- Code Pushdown (moving logic to the database)
- CDS Views (replacing traditional ABAP reports)
- Performance Optimization (in-memory computing)
14. What is an ABAP Proxy?
Answer: An ABAP Proxy enables communication between SAP and external systems using SOAP/Web Services.
15. Explain the Difference Between SELECT and SELECT SINGLE
| Feature | SELECT | SELECT SINGLE |

| Usage | Retrieves multiple rows | Retrieves only one row |
| Performance | Slower (full table scan) | Faster (uses primary key) |
Section 4: Scenario-Based SAP ABAP Interview Questions (2025)
16. How Would You Optimize an ABAP Program?
Answer:
- Use SELECT SINGLE instead of SELECT.
- Avoid nested loops.
- Use FIELD-SYMBOLS for dynamic programming.
- Leverage CDS Views for HANA optimization.
17. How Do You Handle Errors in ABAP?
Answer:
- TRY-CATCH blocks for exceptions.
- SY-SUBRC checks after database operations.
- MESSAGE statements for user alerts.
18. Explain a Real-Time Use Case of BADI
