I would suggest deleting the file from the network drive since they are now in pdmwe. Once you select on drawing it may ask you to locate but once saved it will/should find at the pdmwe location.
If this is not desired, set your referenced documents to look at your pdmwe vault first. Do this by moving pdmwe file folder location to top of list under Tools, Options, File locations, Referenced Documents.
Thanks for the answer, this is exactly as I thought,unfortunately this does not work, the reference does not staychanged, I have checked out the file, checked it in, saved it inevery way I can think of and the file continues to ask me for thefile locations every time I open the assembly.
