EN 16931
FATAL
Every invoice must declare its type (BT-3, cbc:InvoiceTypeCode) with a code from UNTDID 1001 - most commonly 380 (commercial invoice) or 381 (credit note).
How to fix it
- Add
cbc:InvoiceTypeCode380 for a standard invoice. - Use
381for credit notes,384for corrective invoices. - The code must be numeric - words like
Invoiceare rejected.
