I think that is normal behavior. The pdm system is about file management and these assembly does not have a file. The pdm system can't update file relations in SQL database.
i think thats normal too.
Because the virtual assembly contents parts there aren't listed in the SQL database.
That is the ression, if you change the name, the database doesn't know the parts...
The virtual assembly is in an assembly and contains parts that are in the vault (SQL database). Thanks for the reply, though.
