CENTRALIZED PARTS x-reference

i would like to know if possible that when a facility add a cross reference or a new vendor number that this is added to all facility, As this is causing some x-reference issue. SO now i need to check every facility prior to create a new parts( we got a crystal report made to check it faster) but this is still a big issue. We create the parts number in all facility, because we need the number created for the parts kits to work. I am open to best practice ideal to deal with this issue.
