Unassigned Vendors changed to Vendor to be held in Short Buy until ready to cut purchase order.

It would be more efficient to keep orders in Short Buy until ready to purchase them. So you would change the unassigned vendor to the correct vendor you want to purchase from. It would hold that vendor change in short buy until you are ready to purchase. You may have a certain dollar amount to hit before you can purchase from that vendor but it keeps it from all purchasing agents have to look at the unassigned vendor each time they go in short buy.
