Slightly off topic Ramon, but on your BPM's for Part Class and Prod Group. Have you thought about going to Utilities > Extended Properties and under the Part table make those field required? That actually works for us in 9.05.607A.

Subject: RE: [Vantage] Service Connect Error - Need Help!!!
I agree that the error leads you to believe there is a workflow in the update.Part method, but we only have two method directives there. One which requires a part class and one which requires a product group. Haha i know these are from the training module but they are good ones to have! Anyways I turned these off and still got that error. I don't have service connect dong anything with parts so I'm still not sure how got that error.
I'll accept they aren't related I'm sure you guys are smarter than me about the DMT, I haven't ever dug into how it operated. But once i cleared those temp files, it resolved all my errors. So not sure what was going on, very weird...hopefully it never happens again!
