| # Bank reference numbers on purchase invoices For purchase invoices, if the country of the invoice-from business partner is the same as the country of the purchase office, LN requires that you enter the bank reference numbers. LN applies the check indicated by the bank reference number operator in all the sessions in which bank reference numbers are entered or processed. If the bank reference number does not include an operator, by default LN applies the check that you select in the Company Parameters (tfgld0503m000) session. If the bank reference number is not valid, LN displays an error message. If the purchase invoice is finalized, you can still change the bank reference number in the Purchase-Invoice Details (tfacp2100s000) session. Once the invoice is paid, you cannot change the bank reference number. If an invoice is paid in installments, each installment has the bank reference number of the invoice. When LN generates recurring purchase invoices, the bank reference number for each recurring invoice in open entries is left blank. You can enter the bank reference number for generated recurring purchase invoices in the Purchase-Invoice Details (tfacp2100s000) session. The bank reference number is not mandatory for cost invoices. You can use the bank reference number as a selection criterion to select invoices for direct debits. If payments are made through bank files, the bank reference number is included in the payment file or payment document so that the supplier knows which invoice is paid. In the payment files, each bank reference number must be printed on a separate line. To achieve this, you must use a payment method for which you set the Composing Limit to 1 in the Payment/Receipt Method (tfcmg0140s000) session. Related topics Bank reference numbers |
