Creating vendor items
A purchase order vendor is not required to define vendor items.
A vendor item links an item master record, which is a on-stock or inventory item, to a specific vendor. For example, you can view the vendor's stock number for a purchase order. A vendor item can be active or inactive or you can mark it as the default vendor item. An inactive vendor item cannot become the default and cannot be added to a PO line or requisition line.
You can assign multiple vendor items for the same vendor to one item.
