BR-DE-7 — E-Invoice Validation Rule & Fix

Fixture ID: partialContact · XPath: /ubl:Invoice/cac:AccountingSupplierParty/cac:Party/cac:Contact/cbc:ElectronicMail

1. Why This Rule Triggers (Diagnostic Message)

XRechnung requires the element "Seller contact email address" (BT-43). The seller contact group is present but incomplete — BR-DE-5, BR-DE-6 and BR-DE-7 each make one part of it mandatory, so supplying two of the three still fails.

2. How to Fix BR-DE-7

Set seller.contact.email to a monitored mailbox — this is where the authority sends invoice queries.

3. Valid Code / Payload Example

"contact": { "email": "rechnungen@example.de" }
