Invoice type code (BT-3) restricted

What it means

XRechnung restricts the document type code (BT-3): allowed values are 326 (partial invoice), 380 (commercial invoice), 384 (corrected invoice), 389 (self-billed invoice), 381 (credit note), and 875/876/877 (construction-specific).

How to fix it

Set cbc:InvoiceTypeCode (or CreditNoteTypeCode 381) to one of the allowed values; 380 for a normal invoice, 384 for a correction (then add the preceding-invoice reference), 381 for a credit note.
