PEPPOL-EN16931-R005 The VAT accounting currency (BT-6) is "EUR", which is the same as the invoice currency (BT-5)
The VAT accounting currency (BT-6) is "EUR", which is the same as the invoice currency (BT-5). BT-6 exists for exactly one situation: the tax authority requires VAT to be reported in a currency the invoice is not denominated in — a Swedish invoice in EUR reporting VAT in SEK, say. Setting it to the invoice currency states that situation and then contradicts it, and it obliges you to supply BT-111 (BR-53), a second VAT total in a currency that already has one. This is a Peppol BIS Billing 3.0 profile rule: it applies because profile is "peppol-bis-3". It does not apply to the en16931, xrechnung-ubl or xrechnung-cii profiles, whose validators will accept the same document.
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.
