The picture is not Quality control essentials.
Hi,
This QC document is stored within the Document module
This ‘Implemented in Revision’ field is auto populated when you choose to pull through an existing accepted change request from an earlier revision into a new draft during the new draft creation process.
If the change request was against a draft version of a document, then you will be prevented processing a change request until both the document has been activated and the change request is accepted. Change request processing is designed to update active documents, not draft documents.
