This would be helpful for one point of information without having to open the packlist. Most vendor's use the PO number to track an order thru their shop. It would be helpful to be able to search by Vendor ID and see all Purchase orders and packlist numbers for that vendor. The PO can also be used to further refine the search by having the ability to view open or closed PO's. But the ability to search by vendor and see all the information in one place instead of having to open each packlist to see the PO, would keep things very simple and easy to use.
