Invoice type code is missing
What it means
The type code (BT-3) says what kind of document this is — a commercial invoice, a credit note, a corrected invoice. Receivers post these differently, so the field is mandatory.
Can it be fixed automatically?
Nothing about your business is needed to fix this — the correct value is a constant, a code list entry, or is already present in the document.
This one can be repaired automatically. The API applies the fix, re-validates, and reports exactly what changed with before and after values.
How to fix it
For a plain commercial invoice the code is 380, and for a credit note 381. Which one applies follows from the document's root element. Codes such as 384 (corrected invoice) or 386 (prepayment invoice) describe a different intent and must be chosen deliberately.
