Issue - When the value is changed in the Revision the record is displayed with new revision number keeping the CD fields as for previous revision and all the child.
That is all correct, But when the record is saved, there is error "Another process has updated the Record, your changes will be lost"
Why there is a Error

Answer 1

In Acuamtica we have NoteID column unique across the system If you try to create a record with duplicating NoteID field value you'll get "Another process has updated the record" exception because it consider that you are updating the same record.
In you case when you copy revision you do not reset the NoteID value for the record so you actually try to insert another record with the same value.
You'll need to add the following line to CopyRevision method
toGraph.Documents.Cache.SetDefaultExt<EWPMMasterRouting.noteID>(toGraph.Documents.Current);
