Execute Process Group – Error# 1750

Execute Process Group (or Execute Inline Object) fails with the following error message: 

Error#: 1750, Severity: 16, State: 0, Procedure: , Line: 2, Msg: Could not create constraint or index. See previous errors. TableNameDestination: <DestinationTable> 

Answer:
The Inlined object with name <DestinationTable>_Inline probably has PK duplicates. Correct the view so that no PK duplicates exists.
