## Why it fails

- The invoice type code (BT-3) is one XRechnung does not expect, such as `393` (factored invoice) or `325` (proforma).

## How to fix it

- Use `380` for an ordinary invoice, `381` for a credit note, `384` for a corrected invoice, `389` for self-billing, `326` for a partial invoice and `875`, `876` or `877` for construction invoices. It is a warning: other codes are not rejected, but the buyer may not process them.
