Use this dialog box to set up the reason codes for the message code which belongs to the payment method. The reason codes are used for the purpose of giving additional information about the payment transaction which is imported together with the message code from the external payment file. E.g. the code can be a return reason of a return debit note that can be included in the imported payment file. The message code and reason code are displayed in external payments for each imported transaction.
The reason code holds options that are applied to the new customer difference item, e.g. for the purpose of a return debit note, if the transaction is imported from the file with the corresponding reason code. You can enter additional reason codes too, but the codes must be already defined for the payment format in the Payment Format Message Codes window. The reason codes are only available for message codes which are used to create a new customer difference item.
