What does DE-R-009 mean? If both supplier and customer are located in Germany, the element "Buyer post code" (BT-53) shall be provided.

Why did my invoice fail DE-R-009?

When both supplier and customer are located in Germany, the Buyer post code (BT-53) must be provided. Together with DE-R-008 this ensures domestic German invoices carry a complete, addressable buyer location. In UBL the post code is cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cbc:PostalZone.
