BR-DE-1 — E-Invoice Validation Rule & Fix

Fixture ID: emptyXRechnung · XPath: /ubl:Invoice/cac:PaymentMeans

1. Why This Rule Triggers (Diagnostic Message)

XRechnung requires payment instructions (BG-16) with a payment means type code (BT-81). Core EN 16931 leaves this optional, but the German CIUS makes it mandatory so that a public-sector payer can settle the invoice without a phone call.

2. How to Fix BR-DE-1

Set payment.meansCode to a UNTDID 4461 code: "58" SEPA credit transfer, "30" credit transfer, "59" SEPA direct debit, "48" card, "57" standing agreement, "97" clearing between partners. Each code obliges its own group: for 30/58 set payment.iban (BG-17), for 59 set payment.directDebit (BG-19), for 48/54/55 set payment.card (BG-18).

3. Valid Code / Payload Example

"payment": { "meansCode": "58", "iban": "DE02120300000000202051", "accountName": "Acme GmbH" }
