Enqueue Processing
. Detailed Description of the Issue 
In the P01 SAP system, multiple old and inactive enqueue lock entries were observed in transaction SM12. These stale lock entries were causing enqueue contention and had the potential to impact user transactions and background processing. 
 
2. GxP Impact 
Not required at the moment. 
 
 
3. Actions Taken 
 
Reviewed lock details in SM12 to identify obsolete and inactive lock entries. 
Confirmed that the lock entries were no longer tied to active users or running jobs. 
Obtained TAO approval for lock removal. 
Removed the old lock entries from SM12 in the P01 system following standard SAP safety procedures. 
 
 
4. Root Cause 
The issue was caused by stale enqueue lock entries that remained in the system due to abnormally terminated sessions or incomplete process cleanup, leading to outdated locks persisting in SM12. 
 
5. Workaround 
As a temporary workaround, lock entries were monitored in SM12 to ensure no active business transactions were affected until formal approval for cleanup was received. 
 
6. Solution 
With TAO approval, all obsolete lock entries were safely removed from SM12. 
Post?removal checks confirmed that: 
 
Enqueue processing returned to normal 
No further lock contention exists 
System stability and performance are restored 
 
The issue is now fully resolved.
