-Vendors not populating in purchase requisition line when a released product is selected

-We do not get the vendor list to select from even after using allow all vendors, assigning procurement category at item level and also defining the trade agreement.

-Partner wants to be able to see the vendor list to select from when entering item with procurement category in Purchase Requisition Line.

-If we default a vendor at item master level vendor automatically pops up upon selecting an Item with procurement category, but this does not work for partner as they procure material from multiple vendors.
