BR-DE-17: The document type code is not allowed in XRechnung. How to fix it
XRechnung permits only eight values for the document type code (BT-3), and yours is not one of them. This is a warning, not an error.
The rule, in its own words
Mit dem Element "Invoice type code" (BT-3) sollen ausschließlich folgende Codes aus der Codeliste UNTDID 1001 übermittelt werden: 326 (Partial invoice), 380 (Commercial invoice), 384 (Corrected invoice), 389 (Self-billed invoice) und 381 (Credit note),875 (Partial construction invoice), 876 (Partial final construction invoice), 877 (Final construction invoice).
Fields involved: BT-3
What the rule checks
The rule checks the code against a short list: 326 partial invoice, 380 commercial invoice, 381 credit note, 384 corrected invoice, 389 self-billed invoice, plus 875, 876 and 877 for interim and final construction invoices. The European norm allows more; XRechnung narrows it.
Why files fail it
- The software sets a code that is valid in the European norm but not foreseen in XRechnung.
- A code was chosen for a document that is not an invoice, such as a request for prepayment.
- The code is empty, in which case BR-04 applies as well.
How to fix it
- Choose the code that actually describes your document: 380 for an ordinary invoice, 381 for a credit note, 326 for a partial invoice, 384 for a correction.
- In construction, 875, 876 and 877 additionally apply to interim and final invoices.
- This is a warning. The official report accepts the invoice, but the receiving software may post it incorrectly if the code does not fit.
