We are implementing PDM workgroup (secont attempt to do so). The current problem I have is that when purchased items (such as air cylinders, sensors, etc) are checked in they get a revision assigned to them like any other document. When we created a Bill of Materials later that revision shows up on the BOM, we then have to manually delete the revisions. Is there a way to set a flag in PDM workgroup (potentially using VB as I already have a VB interface to add custome properties) to indicate that the document is not revision managed? The only answer I have found thus far is to use "working copy" but, I am afraid the users will abuse the "working copy" scheme and use it for their design parts as well negating the revision managing functions in PDM. I have inquired with my VAR but, they have rarely been useful in answering questions, this group has answered questions much faster and more accurately.
