I know these will seem like a simple issue but I just can't quite seem to figure it out. Our system is set up so that you can only create Change Notices against a Change Request. The problem I have is this, users can create a Change Notice against a Change Request at any state. So the Change Request might be Open, Under Review, Resolved, Canceled etc. What I want to happen is to only allow Change Notices to be created when the Change Request is out of Under Review and is at Implementation. Our workflow sends out a Create Change Notice task when the Change Request reaches Implementation, only then do I want the users to create a Change Notice. Any help would be greatly appreciated.
