If you buy the same item from more than one vendor, you can associate those vendors with the item using the I/C Vendor Details screen.
You can associate up to nine vendors with an item and assign each a vendor type. Assign a vendor type of Vendor 1 to the vendor you use the most.
You also use the I/C Vendor Details screen to enter detailed information about each vendor, including the vendor's item number and the cost of the inventory item.
After you associate a vendor with an item, you can select the vendor's item number when you enter items on requisitions and purchase orders. Purchase Orders displays the cost of the item for you.
Note: Changes you make to the vendor name or contact on this screen do not change the master vendor list. To change the master vendor list, you must make the changes in Accounts Payable.
