In IV while editing a BOM I need the ability to check out a file from Vault. Currently while in the BOM editor if I want to modify the propertirs of a file I need to get out of the editor and open the file, check it out and then switch back to the assembly and open the BOM again, make my edit....repeat. It makes for a much smoother woprkflow to be able to check out the file directly from the editor and check it in as well.
It's true that many of these edits could be made in vault IF the UDPs editable and mapped which is not always the case. Some companies have decided to edit iprops only in IV. Also, if I'm over riding a qty or changing BOM structure I must do that in IV.
