In Procurement Categories, there should be the ability to assign a default Over/Under spend % to allow users to partially receipt and close a purchase order for further receipt.

Within Procurement and Sourcing where using Products are not a feasible option (i.e. purchasing mainly ad-hoc with frequently changing suppliers, products and prices) this would allow for a default to be set for all PO's rather than having to manually add on each PO line.

Similar functionality is available as a default on Procurement Product but not on a Procurement Category currently.
By adding as a default on the category rather than by manually adjusting on every PO line it would add a control aspect as this could be a standard tolerance.
