We faced an issue in DTP load in BW after the Migration of Database from Oracle to HANA.
Issue: The DTP load from source DSO to target DSO was failing.
Error Message: Serious error occurred: Cannot set database lock
Serious error occurred: 2048 column store error: bw precheck acquire lock failed
column store error: bw precheck acquire lock failed:  Entries are locked.
Analysis: There was a red request in the target and the DTP was repeated without deleting the red request which led to the above error message.
Solution: The red request was deleted and the DTP was repeated.
