The SDD Rulebooks currently require that the payment message sent by the creditor’s bank to request a direct debit collection specifies whether the transaction is a first, one-off, recurrent or last collection. These specifications are also referred to as ‘sequence types’. The SDD Core Rulebook version 9.0 and SDD B2B Rulebook version 7.0 have been amended to simplify the use of sequence types by making the sequence type “first” optional. This change does not impact creditors collecting SDD payments.
