Release : 4.7
Component : CA Test Data Manager - TDM Web Portal
When there is only one Environment defined, before you can delete the Environment, you must first delete the corresponding model. Another option would be to create a new Environment, and then delete the old Environment that you no longer want. Engineering provided TDMWeb-18.104.22.168 patch, which improves the messaging to indicate why the deletion of the Environment failed.
