Top ABAP on HANA Interview Questions and Answers
Preparing for an SAP ABAP on HANA interview? Understanding traditional ABAP is important, but modern interviews increasingly focus on how ABAP works with the SAP HANA database, performance optimization, CDS views, AMDP, and code pushdown.
Here are some important areas to prepare before your interview.
1. What is ABAP on HANA?
ABAP on HANA refers to developing and optimizing ABAP applications for the SAP HANA in-memory database.
The key idea is to move data-intensive operations closer to the database instead of processing everything in the ABAP application layer.
2. What is Code Pushdown?
Code pushdown means moving data-intensive calculations and processing from the ABAP application server to the SAP HANA database.
This can reduce data transfer and improve application performance.
3. What is a CDS View?
Core Data Services (CDS) provides a data-modeling approach for defining reusable data models.
CDS views are widely used in modern SAP development and can support efficient data access and semantic modeling.
4. What is AMDP?
ABAP Managed Database Procedures, or AMDP, allows developers to implement database procedures that execute directly on SAP HANA.
AMDP is particularly useful when complex database-side processing is required.
5. What is the Code-to-Data Paradigm?
The code-to-data approach means bringing the processing closer to the data.
Instead of transferring large amounts of data from HANA to the application server and processing it there, appropriate operations can be performed in HANA.
6. What are ADT tools?
ABAP Development Tools (ADT) provide an Eclipse-based development environment for modern ABAP development.
Developers can use ADT for working with objects such as CDS views and other HANA-oriented ABAP development tasks.
7. How can you improve ABAP program performance on HANA?
Some important techniques include:
- Avoiding unnecessary database access
- Selecting only required fields
- Using efficient SQL statements
- Reducing unnecessary data transfer
- Using CDS views where appropriate
- Using AMDP for suitable database-intensive scenarios
- Monitoring SQL performance
- Following clean and efficient coding practices
8. What is SQL Monitor?
SQL Monitor can help identify SQL statements executed by ABAP programs and analyze their runtime behavior.

It can be useful when investigating database-related performance issues.
9. What is the difference between traditional ABAP and ABAP on HANA?
Traditional ABAP development often relies heavily on application-server processing.
ABAP on HANA encourages developers to take advantage of HANA’s in-memory processing capabilities and use techniques such as CDS, AMDP, and code pushdown.
10. What should you prepare for an ABAP on HANA interview?
Focus on these areas:
- ABAP fundamentals
- New ABAP syntax
- SAP HANA fundamentals
- SQL optimization
- CDS Views
- AMDP
- Code pushdown
- ADT and Eclipse
- Debugging
- Performance analysis
- Database access
- S/4HANA development concepts
Final Thoughts
ABAP on HANA interviews generally test both your ABAP programming knowledge and your understanding of HANA-oriented development.
Rather than memorizing interview questions, focus on understanding why a particular technique is used and when it is appropriate. Practical knowledge of CDS views, AMDP, code pushdown, ADT, and performance optimization can help you explain your technical approach more clearly during an interview.
If you are preparing for an SAP ABAP on HANA career, hands-on practice is an important part of building confidence and understanding modern SAP development.
