(Doc ID 1315735.1)

Applies to:

Oracle Project Planning and Control - Version 12.1.3 and later
Information in this document applies to any platform.


The process PRC: Process Project Structure Updates is scheduled as part of a request set that runs nightly. Sometimes there are multiple calls to the program from within the same set iteration resulting in the following error:

ORA-00001: unique constraint (PA.PA_PROGRESS_ROLLUP_U2) violated.

How can we avoid the unique constraint error?
