DE-R-015
What does DE-R-015 mean? If both supplier and customer are located in Germany, the element "Buyer reference" (BT-10) shall be provided.
Why did my invoice fail DE-R-015?
For domestic German invoices, the Buyer reference (BT-10) is mandatory. In Germany this field carries the Leitweg-ID or another buyer-assigned routing reference and is required so the invoice can be routed and booked by the recipient (it is the hallmark requirement of XRechnung). In UBL it is the top-level cbc:BuyerReference element.
