What would be the criteria for tagging? If it is only location, I don't see how you would be able to do it automatically, since the software would have to be able to 'know' the location
Is there some other value that can be checked to determine what the tag should be?
Also - could you explain what information the manufacturing department needs? I.e. if a part is used in multiple locations, are we talking about things like bolts and nuts here? That would be a good example of parts being used in multiple locations. Only potential problem I see here is that the data management can quickly become a job on its own, which is something we all try to avoid
IMHO it would be better to plonk down an old PC on the floor and have eDrawings installed with minimal vault access. But of course that needs to go through a whole approval process by itself
