A healthy SAP system is rarely an accident. It is usually the result of someone checking the same things, the same way, every week.
The checklist
| Area | Transaction | What to look for |
|---|---|---|
| Short dumps | ST22 |
Repeated dumps from the same program |
| Background jobs | SM37 |
Cancelled or long-running jobs |
| Lock entries | SM12 |
Locks older than a day |
| Update errors | SM13 |
Any failed updates |
| System log | SM21 |
Errors and security warnings |
| Work processes | SM50 / SM66 |
Processes stuck in one state |
| Spool | SP01 |
Very large or failed spool requests |
| Database | DB02 |
Tablespace growth and missing indexes |
| Users | SU01 / SUIM |
Expired or unused privileged accounts |
| Transports | STMS |
Failed imports in the queue |
Turning it into a habit
Put the checklist in a shared document, record what you find each week, and review the trends monthly. Recurring issues become obvious, and the next engineer inherits context instead of surprises.
