Background job error - ORA-0001: unique constraint

Hi Folks

While trying to run a background job we are facing following error message :

"ORA-0001: unique constraint (SAPSR3DB.SYS_C006045) violated"

We have already tried the suggestion in:

Thread: CC 5.2 - Problem Schedule BgJob: ORA-00001: unique constraint

CC 5.2 - Problem Schedule BgJob: ORA-00001: unique constraint

without any luck.

We are on Access control 5.3. Any sugguestions for a solution will be appreciated.

Kind regards

Arif
