Monitoring and Troubleshooting ABAP Systems

ABAP troubleshooting pocket guide

• Loop: observe → hypothesize → test → confirm. Write it down.
• Observe: system, client, front end, user, time, frequency, what changed, a working comparison case.
• Hang: SM66 then SM50 (type, status, reason, time, program, user); SM04 for sessions; dpmon if you cannot log on.
• Dumps: ST22 error name, analysis, termination point; match SM21 by time and instance.
• Locks: SM12 owner and age; check SM13 before deleting any lock.
• Updates: SM13 failed request → fix cause → repeat or delete with the process owner.
• Slow: ST05 for SQL (slow, repeated, huge results); SAT for ABAP time.
• Authorizations: SU53 for the last failure; STAUTHTRACE for a whole process.
• Classify: environment, data, configuration, code, test; attach evidence; rerun environment failures before sign-off.
