I have a requirement where need to creare new program that updates PO prices. At start program should ask delivery date, item and vendor. Then program will search all POs matched by the search criteria. Then program will ask one by one price of items but only once per item. Program should display old price when asking new, this should reduce amount of user errors. After price update, program should print changed items and also new and changed price.
Can any body help to achive this, is there any function module ?
