FRST / RCUR / OOFF / FNAL
SEPA direct debit sequence codes: first, recurring, one-off or final.
FRST first collection of a mandate. RCUR subsequent collections. OOFF one-off (non-recurring mandate). FNAL last collection planned.
Since November 2016 FRST is optional: the first collection on a mandate may also be sent as RCUR, and every sequence type has the same D-1 business day deadline. GenerateSEPA writes RCUR on every collection.
