In PO Forms, when a buyer enters an PO line item the buyer can select Catalog and determine if a Blanket Purchase Agreement or Active Quote exists for this item. As well as also checking prior purchases. Where is this feature/option  in BWC?  It appears there is no way of knowing if an item has a pre-existing BPA or supplier quotation in BPA (unless one knows the BPA supplier name). In PO forms  BPA's,  Quotations and prior Purchase History is visible  without a buyer having to remember or know the BPA/ Quotation supplier .  This seems like a major loss
