The Warehouse Vendors module allows you to document your vendors and the parts/materials they provide. From here, you can make a vendor restricted by marking the Restricted PO List checkbox (in the Contact tab). When a vendor is restricted, you can only create purchase orders for the parts associated with the vendor (i.e. listed in the Vendor Parts tab of this module).
