0PM_DS11 Update not possible. Package contains duplicate entries
The datastore 0PM_DS11 was activated from business content,no issue with that process.
The data update process fails from an unknown reason, the transformation return a duplicate entries message when try to update dso 0PM_DS11 from 0PM_DS12
Doing debugging in the end routine the result_package has no duplicate records, in the end routine the function RS_BW_BCT_KEYFIGURE_ARRAY_GET, returns all the information with the 0PM_D11 key fields populated no duplicate records there, but the error message is triggered.
Another extra information, system version SAP BW 7.4 SP 9
Business content version 757 SP 4
