Internal data errors

These error codes are sent to you when you transfer incorrect data about the creditor, a file in an invalid format or transactions incorrectly sequenced. When receiving one of these error codes, you have to try and fix the data in your database or file, and then submit the request once again.

Proof code	Description	More details	Required actionAction
AM05	Duplicate direct debit	Collection has already been made. This can either be caused by a wrong transaction ID, or because two FIRST transactions have been submitted.	Verify the collection really is duplicated.
BE05	Creditor’s ID incorrect	The given creditor’s ID is incorrect or not valid.	Fix the creditor’s ID and submit your request once again.
FF01	Transaction code incorrect or file’s format invalid.	A mandatory field is missing in your order file, or one of the fields is not compliant with the interbank specifications.	Repare the XML file.
FF05	Incorrect direct debit type	The drect debit type shows a value other than COR, COR1 or B2B.	Verify the direct debit type.
MD02	Missing or inaccurate mandate data	The mandate data given by your client are incorrect or there are missing elements.	Update the missing or incorrect information.
RR03	The creditor’s name or adress required by the regulation is incorrect or missing.	Your name or adress is missing. You can verify by yourself before transfering it.	If information is missing, modify the direct debit and submit the request once again. If it is a regulatory error, contact the client’s bank.
AG02	Incorrect transaction code, or sequence error	The sequence type is not compatible with previous direct debits. For example, you send a RCUR payment to a client with no previous FRST payment.	Correct the wrong information and try again.
MD01	No valid mandate or operation not authorized	The mandate is not valide anymore on the client’s account. When it is sent as a response to a RCUR payment, the mandate has been canceled by the client and can not be restored. If not, the mandate may have expired, if not used for 36 months. It is also used when a client asks for a refund, declaring this operation had not been authorized. This can happen until 13 months after the payment.	Verify a valid mandate is set up. In the case of a refund, contact your client for more details.
