CIF queues - Lock not possible error in application log

hi,

Below is the application error log from SLG1

Looks when R3 is sent CIF queue, could not be processed at APO, due to lock not possible. It looks, the object is already locked.

This happens only certain hours only. We searched in batch jobs etc across landscape, but no luck.

We are currently checking, if this could be due to some issues with LiveCache processing.

Any input would be helpful.

SLG1 - Application log errror:

Source system: sapapp80 user: R3CIFRFC transaction: function module: /SAPAPO/CIF_CLAF_INB

Access block: data from system CLAF updated again

Lock not possible for charc at FM claf_inb:000000000100020361G21C02244Z

Object is locked at present

Thanks,
