This question assesses your technical ability to troubleshoot SQL/ABAP queries and understand SAP data structures, which are foundational for junior developers.
How to answer
- Start by outlining the steps to reproduce the issue (e.g., input parameters, expected vs. actual results)
- Explain how you would use SAP transaction SE38 or SE80 to examine the code
- Describe how you would check table structures (SE11) and data types for inconsistencies
- Demonstrate knowledge of debugging tools like F5/F6/F7 or breakpoints
- Show how you would validate data flow between the database and the report logic
- Include testing and verification steps after making corrections
What not to say
- Claiming the database is always correct without verifying
- Skipping detailed debugging steps and jumping to hypothetical fixes
- Failing to explain how you would verify the fix with test data
- Using incorrect or outdated SAP transaction codes
Sample answer
“First, I'd run the report in debug mode (F5) to step through the SELECT statements and examine variable values. At my internship with Accenture, I once found a missing JOIN condition in an ABAP report by comparing the SQL trace (transaction ST05) with the table maintenance (SE11). After correcting the field mapping, I tested with sample records from SE16 and confirmed the data output matched the requirements.”
