It appears that SAP calculates "unit price" on a PO by using the price list and "unit price" from the item master card. This calculation will rarely result in the true purchase price for vendor/item combination. So for example if vendor Ace last purchased item X for $100 and vendor Beta last purchased item X for $70 then those are the prices that I would expect to default onto a PO for each of the 2 vendors. SAP doesn't have the ability, correct?
Also, i created an item for testing and I can't get it to appear in the PO item lookup for any vendors. It doesn't even appear for the preferred vendor I assigned to it. Any help on this?
