Hello,
First as Diana said, you'll need to make sure all users are not processing the data during DP background job run.
Sometimes liveCache lock may remain incorrectly and unexpectedly due to process termination.
If you encounter locking error in DP processing, first check lock table SM12. If there's nothing relevant in SM12, there still maybe some undeleted liveCache locks. You can delete liveCache locks with the reports:
- SLCA_LCK_SYNCHOWNERS
- /SAPAPO/OM_DELETE_OLD_SIMSESS
Best Regards,
Ada
