Hello,

Item list price defined in Item master and child organization, in PO selected deliver to location,  for this org, list price entered in item attribute,  in PO line, the list price is not getting default, we could see there are  Base price and Price, can anyone explain what is the difference between base price and Price and is there any setup we need to perform apart from list price to default the price in PO

Even in requisition also the price is not getting defaulted.
