Retrobilling

If the price of a purchase contract or an item is modified because of price renegotiations, the retrobilling functionality can be used to re-invoice the previously invoiced items for purchase orders or schedules. Price differences are handled using price change advice lines, which are based on the purchase payable receipts of the order or schedule. After approving and processing a price change advice line, an additional (retro-active) payable receipt line is generated for the order or schedule.

  Before you can use retrobilling, you must specify the retrobilling master data. Next, you can generate, approve and process price change advice lines and invoice the Retro-Active purchase payable receipts that result from this process.
