I've got a real head scratcher for you. I was not sure if I should put this in Model or Datamanagement. We'll start here.
My client is working in PDM3.7, and a real early build of 2001(2001280) with no plans to pay maintenance for upgrades. They are going to another CAD system.
I have a drawing with a sub-assembly associated with it that was probably created in 2000i and placed in PDM several years ago. It has undergone several versions (1.0 to 1.9). At version 1.6, an instance of the drawing was place in PDM! How can this be? As you can't have a generic drawing with an instance that I know of in Pro/E or PDM.
I fetched the drawing and made a change. When I try to resubmit the drawing, it drags along this drawing (instance). Of course PDM say's no can do with database errors, etc.
So I created a new drawing (filename_test.drw) and merged the bad one in, and I can submit that in PDM no problem and no instances. Great. I'll rename the bad one "_bad" and rename the new one as the drawing number. Nope...I get database inconsistencies and errors. I've tried to delete versions, Delete all versions, remove the dependency, rename, and trying to force (over-ride) the new drawing as 1.10. All have had the same issue of Database errors and it also has locked up PDM at the server with TR_SAVE history directories, requiring me to delete them and sometimes start and stop the processes. A look at the PDM logs shows that it recognizes this as a generic drawing and flags (invalid type for Generic and instance).
I've also tried to simulate this on two drawings in PDM by adding dependencies. They show up as "USER DEFINED" and are breakable. This problem drawing is dependency is "GENERIC" and "INSTANCE" for the sub drawing.
It appears this sourced from Pro/E. How I don't know. Also, every time I've done a Database checkup, it has crashed the server. This database is on its last leg unfortunately. I need to keep it alive until the end of the year.
I've search everywhere in both Pro/E and PDM on how to create, or remove this situation with no luck. The Client does not have PTC support and since it's related to PDM, I don't think they would really want to look at it in depth.
Has anyone ever seen a drawing that is a generic and a drawing under it as an instance? Any ideas of how to delete it from the system? We don't mind loosing the old revisions as long as the new file functions.
