Buyer reference / Leitweg-ID (BT-10) required

What it means

XRechnung requires the Buyer reference (BT-10) — for public-sector invoices in Germany this is the Leitweg-ID that routes the invoice to the right authority.

How to fix it

Set cbc:BuyerReference (UBL) / ram:BuyerReference (CII) to the Leitweg-ID the public buyer gave you (format like '991-12345-67'). Don't leave it empty.

Example

<cbc:BuyerReference>991-12345-67</cbc:BuyerReference>
