XRechnung
FATAL
XRechnung makes the buyer reference (BT-10) mandatory - in Germany it carries the Leitweg-ID, the routing identifier that steers the invoice to the right public authority.
How to fix it
- Add
cbc:BuyerReferencewith the Leitweg-ID the buyer communicated (format like04011000-1234512345-06). - No Leitweg-ID, no payment - request it from the contracting authority before invoicing.
Official rule text
Das Element "Buyer reference" (BT-10) muss übermittelt werden.
Developers also reach this page searching for an “XRechnung validation error”, a “German e-invoice rejected” message, or how to correct a failed ZUGFeRD/Factur-X-style check — it's the same issue, explained above.
In short, in English: The element "Buyer reference" (BT-10) must be provided.
