SAP Troubleshooting hub
This troubleshooting hub covers the recurring problems in SAP operations, dumps, RFC and IDoc errors, transport and authorization failures, performance, printing and background-job issues, with a methodical, evidence-first approach.
SAP troubleshooting is a method: read the evidence first, the dump in ST22, the system log in SM21, the job log in SM37, the IDoc status in WE02, then work down the likely causes, fix the root cause and change one thing at a time. Each page in this hub takes one symptom and lists causes and fixes in order.
- ST22, ABAP dumps (crashes).
- SM37, background jobs; SM13, updates.
- Watch out: Guessing instead of reading logs/dumps.
The troubleshooting method
Effective SAP troubleshooting is disciplined: read the evidence (the dump in ST22, the log in SM21, the job log, the IDoc status), identify the most likely cause, fix the root cause (not just the symptom), and change one thing at a time so you know what worked.
The core diagnostic tools
- ST22, ABAP dumps (crashes).
- SM21, system log.
- SM37, background jobs; SM13, updates.
- WE02/BD87, IDocs; SM59, RFC.
- SU53/STAUTHTRACE, authorizations; ST03/ST05, performance.
Using this module
Each page addresses one symptom with likely causes and fixes in order. Go to the page for your symptom, start with the evidence it points to, and work down the causes rather than guessing. Fix the root cause and confirm.
Common pitfalls
- Guessing instead of reading logs/dumps.
- Symptom fixes that recur.
- Changing many things at once.
