How to Delete a Closed Document Change Control (DCC) in a Quality Vault that is Referenced in a Document
Deleting a Closed DCC is not a usual action in a Production environment, but if it needs to be done, here is the solution:
The DCC record can not be modified and the document reference to the DCC can not be removed either, unless the DCC record is moved to another state.
A temporary User Action may be needed for this change. Once it is configured, the DCC becomes editable and the reference to the document can be removed, and the DCC record can be deleted.
