Issue/Introduction

The Load Data Warehouse (DWH) job fails with the following error:
[CA Clarity][Oracle JDBC Driver][Oracle]ORA-02437: cannot validate (PPM_DWH.DWH_INV_TEAM_PK) - primary key violated
ORA-06512: at line 7

Environment

Release: Any
Component: Data Warehouse

Cause

Caused by a duplicate team record on a project.

Resolution

The duplicate record cannot be deleted via the UI, and must be done via the database. You must ensure that the record that is being left in place (the one NOT being deleted) must point to the proper team_id.

1. Run the following query against the Clarity database:
   
   select odf_pk, count(odf_pk) from dwh_team_v 
group by odf_pk 
having count(odf_pk) > 1

This will show you the ones that have duplicates.
2. Take the "odf_pk" values from the results and put them into this query inside the parentheses, and run this against the DWH database:
   
   select * from dwh_team_v where odf_pk in (PUT_LIST_OF_ODF_PK_VALUES_HERE )
   
   This will show you the specific projects that have duplicate teams.
3. You can then delete the duplicate records from both the prassignment and odf_ca_assignment tables.
   IMPORTANT:  Ensure the records you are leaving are the ones pointed to the proper value!! As always, we recommend testing this in a test environment before attempting to do this in production.  Additionally, ALWAYS backup the database prior to deleting any records.
