warningPeppol BIS Billing 3.0profileUBLBT-3
The element "Invoice type code" (BT-3) should only contain the following values from code list UNTDID 1001: 326 (Partial invoice), 380 (Commercial invoice), 384 (Corrected invoice), 389 (Self-billed invoice), 381 (Credit note), 875 (Partial construction invoice), 876 (Partial final construction invoice), 877 (Final construction invoice).
The invoice type code (BT-3) is outside the restricted set XRechnung accepts.
Use one of 326 (partial invoice), 380 (commercial invoice), 384 (corrected invoice), 389 (self-billed invoice), 381 (credit note), 875, 876 or 877 (construction-industry invoices). This is a warning, so the invoice passes - but a receiver may still reject it.
