The related Material Code must be entered into the invoice line in order to match the Price diff. invoices (issued) with the sales transactions. The matching operation can be performed only after the code entry, and separately for each line. If the price difference will be applied to the bottom of a specific Sales Invoice, all the invoice lines are transferred using the Invoice Transfer option located in the Operations menu, instead of transferring the lines one by one. The invoices are matched with the sales transactions by invoice date. The start and end date range is entered. The sales invoices to which the material in Price Difference Invoice (Issued) belongs are listed with number, date, invoice type, document and total information. The invoices to be transferred are selected by checking. The information of the lines of the selected invoice is directly transferred into the lines of the Price diff. invoice (issued). If the sales invoice to be transferred contains material lines for which period closing is applied, and if the invoice is approved, the invoice is not transferred into the Price Difference Invoice.
