BR-49 The invoice carries a payment instruction group (BG-16), so it must specify the payment means type code (BT-81)
The invoice carries a payment instruction group (BG-16), so it must specify the payment means type code (BT-81). BG-16 is optional in core EN 16931 — but once present it has to be actionable, and the means code is the part a payment system reads. An IBAN with no means code does not tell the payer whether you expect them to push a credit transfer or whether you intend to collect by direct debit, which are opposite instructions.
This rule is implemented and its error payload below is real, but the long-form write-up — normative text, worked example, divergence note — is not written yet. Everything the library knows about this rule is on this page. Ask and we will prioritise it.
