Hi @NavinBamane ,
If you control the database (self-hosted):
Connect to your Campaign database directly
Run the following SQL to identify problematic entries:
SELECT * FROM NmsTrackingUrl WHERE iType = 2;
You should see more than one row—there should be only one, decide which record to keep.
Usually, the oldest or the one with the lowest itrackingurlid should be retained.
Delete the extra entries:
DELETE FROM NmsTrackingUrl WHERE iType = 2 AND itrackingurlid = [ID-to-delete];
Restart the database cleanup workflow in Adobe Campaign Classic.
If you are on the Adobe Cloud (managed by Adobe):
You cannot make DB changes directly.
Raise a support ticket and ask Adobe support to perform this cleanup for you, referencing the exact error.
Regards,
Abhinav
