Interview Questions – Beginner to Advanced

1. Interview Questions for Freshers

Q1. What is SAP ABAP on HANA?
Answer:
SAP ABAP on HANA combines traditional ABAP programming with SAP HANA’s in-memory database technology. It supports the code-to-data paradigm, Core Data Services (CDS) views, SQLScript, and ABAP Managed Database Procedures (AMDP) to enhance performance.

Q2. How does ABAP differ from ABAP on HANA?

Q3. What is meant by Code Pushdown?
Answer:
Code pushdown involves shifting processing logic from the ABAP application layer to the HANA database. This reduces data movement and improves efficiency. For example, instead of retrieving all records and filtering in ABAP, filters are applied directly in CDS views or SQLScript.

2. Interview Questions (2–5 Years of Experience)

Q4. What are CDS Views in SAP ABAP on HANA?
Answer:
CDS (Core Data Services) views allow data modeling directly on the database layer. They support:

• Reusability

• Annotation-based UI generation

• Improved performance with optimized SQL

Types:

• DDL CDS: Created at the database level

• ABAP CDS: Integrated with the ABAP layer

Q5. What is AMDP, and how does it differ from SQLScript?

Q6. How do you improve the performance of ABAP reports on HANA?
Answer:

• Use CDS views over standard SELECTs

• Apply code pushdown wherever possible

• Replace nested loops with JOIN operations

• Utilize HANA-specific functions like CE functions

3. Interview Questions (5–10 Years of Experience)

1. ABAP Application Layer – for business logic

2. HANA DB – for in-memory data processing

3. Code Pushdown Layer – includes CDS, AMDP

4. UI Layer – modern UIs built using SAP Fiori/UI5

Q8. What are some limitations of ABAP on HANA?
Answer:

• Older ABAP code may not be optimized for HANA

• Debugging AMDP is complex and tool-dependent

• Licensing for HANA may be cost-prohibitive

Q9. How do you migrate an existing ABAP program to HANA?
Answer:
Steps include:

1. Run a readiness check with the Code Inspector

2. Refactor SQL for HANA optimization using CDS/AMDP

3. Benchmark performance before and after migration

4. Test thoroughly and deploy the updated version
