Hello fellow community members,
Today I wanted to inform the communities of a known issue and its resolution:
Error: ORA-02270: no matching unique or primary key for this column-list
Error ORA-06512: at "PPM_DWH.CMN_ENABLE_DISABLE_SP", line 67 during patch installation or upgrade
or Error: ORA-02270: no matching unique or primary key for this column-list ORA-06512: at "PPM_DWH.CMN_ENABLE_CONSTRAINTS_SP", line 10 during Load Data Warehouse job run
Here is an example of the full error during upgrade:

The root cause is the Load Data Warehouse job had failed, so the PK were disabled by another stored procedure CMN_DISABLE_CONSTRAINTS_SP, but not reenabled back. Or if it happened after refresh, the services were not stopped and the job was running when the backup was taken.
If you're upgrading:
- After a full database rollback, run Load Data Warehouse job - Full until successful completion (fix any errors on the way)
- Re-run the upgrade/ patch installation once the job is successful
If you're facing this whilst running the Load Data Warehouse job:
1.Run the following SQL query to reenable the constraints back on the Data Warehouse database:
-- Enable PK constraints and log the exceptions into the dwh_fk_pk_exceptions table
FOR I IN (SELECT TABLE_NAME, CONSTRAINT_NAME
WHERE STATUS = 'DISABLED'
AND CONSTRAINT_TYPE = 'P'
EXECUTE IMMEDIATE 'ALTER TABLE ' ||I.TABLE_NAME|| ' ENABLE CONSTRAINT ' ||I.CONSTRAINT_NAME || ' EXCEPTIONS INTO DWH_FK_PK_EXCEPTIONS';
END LOOP I;
- Once done, re-run the Load Data Warehouse job
This SQL solution can also be used with upgrade issues just ensure you do a full database rollback before running the query.
The issue is logged as CLRT-80494.
