AG02 Operation code/transaction code/sequence type incorrect, invalid file format

Occurs when?

Recurrent after a one-off payment (RCUR after an OOFF). A one-off after a recurrent payment (OOFF after a RCUR). Incorrect identification code for the operation (at service level or local instrument).

Possible root cause

Creditor: Technical error or error due to the transaction process or file (sequence type).

What can you do?

Correct the incorrect information. If the error is due to the software package, fix it. Close a recurring mandate with the debtor if you have used the one-off type. Twikey recommends using one-time transactions as little as possible.
