I've been running into an inconsistent bug with assemblies containing virtual parts. When I make the parts in the assemblies virtual, it renames them to "Copy of part #^assembly #", and I go through each virtual part to modify the part # in the custom properties to show only the part number itself, without the number of the assembly. This allows the BOMs on my drawings to appear correctly. However, when I attempt to check the files into EPDM, sometimes the virtual part numbers will randomly revert from the number I input manually to the $PRP:"SW-File Name" it wanted to be originally. The error doesn't happen every time, to make matters even more frustrating, and usually if I check the file back out and edit the part number again it will remember it and properly appear on the drawing.
It's a really weird error and while it's possible to work around it as described above, it's a huge waste of time and very frustrating.
Assembly file and corresponding drawing attached. Again, these files were correct until I uploaded them to EPDM.
Thanks for your help!
