When the Source field on the Items form, General tab shows that the source for this item is Purchased and the Create PO Reqs from PLN field in the Planning Parameters form is selected, the system firms each selected planned order into a line on a purchase requisition.
If you know the vendor number, enter it in the Vendor field.
NOTE: By default, the system assigns the item's first-ranked item/vendor cross-reference. If you leave the Vendor field blank, and if no item/vendor cross-reference exists, the system creates the requisition with no vendor assigned to this item.
