Introduction
Knowing the SAP ABAP syllabus is different from being able to explain and apply it during an interview. Interviewers may ask about programming logic, internal tables, Open SQL, reports, debugging, object-oriented ABAP, enhancements, interfaces and modern S/4HANA development. This guide covers common SAP ABAP interview questions for freshers and experienced candidates.
SAP ABAP Interview Preparation
Most SAP ABAP interviews start with programming and SAP fundamentals before moving into database access, reports, debugging, object-oriented development, enhancements and scenario-based questions.
Instead of memorizing definitions, prepare to explain what a concept does, why it is used, how you would implement it and how you would troubleshoot common problems.
Practical project experience is useful because technical interviewers can ask candidates to explain what they personally developed.

- •Practice internal tables
- •Revise Open SQL
- •Practice reports and ALV
- •Use the debugger
- •Revise OO ABAP
- •Understand enhancements
