Error: object "EPC Number" locked by another process

In a particular ALE we are sending to AII from outisde SAP... we are sending some 2000+ EPC's to hit the AII. This is a real life situation which we are testing.

The ALE messages are sent every 4 mins for various processes like Load, Unload, Pack etc.

Now after analyzing the logs we found that all were showing errors and in all the lots one particular epc is locked. The error message reads..

"Object urn epc..... 3992 is locked by another process; try again later"

Now this same EPC is shown as lock error in all the sets. And none of the EPC's sent in the ALE reached AII and EM later.

Now our inference was since once EPC is blocked.. the whole lot got blocked.

And another issue is " How do we unlock this EPC and the process" Is there any method.

We also check SM 58 to see transactional RFC's and did F6 to execute those that were in Que.

Does the System be able to take 2000+EPC's in one ALE at a single go every 5 mins for various Processes like Load , Pack etc.

Hello Ramachandra,

Opening this very old message as we too are facing the same issue.

Could you please share your solution or any guidance.

1. How do you know which process locking the object?

2. This looks like an issue when the payload is more than a certain tolerance. How do you work around this constraint?

Regards
