When you apply the hotfix, the Test Data Management and test data warehouse repository version tables create an entry for the version. The roll back does not delete the version entry. You must manually delete the entry for the version.

Open the Test Data Management repository database in the database client and run a query to search for data in the ILM_VERSION table.
For example:
Select * from ILM_VERSION
Delete the entry for the hotfix version.
Restart the Test Data Manager Service.
If you have a test data warehouse, open the test data warehouse repository database in the database client and run a query to search for data in the TDW_VERSION table.
For example:
Select * from TDW_VERSION
Delete the entry for the hotfix version.
Restart the Test Data Warehouse Service.
