Debug ABAP in SAP how-to guides

Debug ABAP

Debugging lets you step through ABAP and inspect data at runtime. This guide shows how to start and use the debugger effectively.

Quick answer

The skill is breaking in the right place, use a breakpoint on the error message or exception rather than stepping through thousands of lines.

Key takeaways

Set a breakpoint: in the editor (ADT/SE80), or type /h in the command field before running a transaction.
Run the program/transaction; execution stops at the breakpoint.
Step through with F5 (into), F6 (over), F7 (return); inspect variables and internal tables.
Watch out: Following steps without understanding the concept.

Step by step

Set a breakpoint: in the editor (ADT/SE80), or type /h in the command field before running a transaction.
Run the program/transaction; execution stops at the breakpoint.
Step through with F5 (into), F6 (over), F7 (return); inspect variables and internal tables.
Use conditional/statement/exception breakpoints to break at the right place (e.g. on a message or exception).
Fix the issue in code (in DEV), then re-test.

Notes and tips

The skill is breaking in the right place, use a breakpoint on the error message or exception rather than stepping through thousands of lines. Watchpoints break when a variable changes. Be careful changing values, especially in production (tightly controlled). Reading ST22 dumps complements debugging.

Common pitfalls

Following steps without understanding the concept.
Skipping testing in a non-production system.
Applying blindly to a different scenario.
