Original rule text
[DE-R-002]-If both supplier and customer are located in Germany, the group "SELLER CONTACT" (BG-6) shall be provided.
cac:Party/cac:ContactDE-R-002 is a fatal rule in the country layer of Peppol BIS Billing 3.0.21 · UBL. An invoice that breaks it is rejected. It refers to BG-6.
What this rule requires
When both the supplier and customer postal addresses have country identification code DE (case- and whitespace-insensitive), the rule requires the supplier party to contain cac:Party/cac:Contact inside cac:AccountingSupplierParty. This is the UBL element for the "SELLER CONTACT" (BG-6) group. A document fails validation if both countries are DE but the supplier cac:Party has no cac:Contact child.
How to fix
Add a cac:Contact element inside cac:AccountingSupplierParty/cac:Party with the supplier contact details required by BG-6 (for example, name, phone, email). The rule only checks that the element is present, not its content. Ensure your system generates this element when both parties are located in Germany.
