Unique constraint violations error in ADM



User was consistently getting ADM errors (unique constraint violations) while updating some of their FACT tables. 

Error Messages

ORA-00001: unique constraint (NANBA.PR_DATA_DM_ADMMART_MDL_FACT_PK) violated

Steps to Reproduce

Install Pega DSM and ADM. Perform Decisioning use-case that updates ADM.

Root Cause

There were duplicate ADMSnapshot agents defined.


Disabling ADMSnapshot agent defined in the custom ruleset and starting only the out-of-the-box (DecisionEngine) ADMSnapshot agent has helped resolve the issue.
