BR-CL-01: The document type code is not an allowed value
This code shows up when an electronic invoice is validated. Here is what it means, why it fires, and what to change in the file.
Why this code appears
The document type code (BT-3) is not in the UNTDID 1001 subset retained by the standard. An invented code, or an order code used on an invoice, is refused.
How to fix it
Use 380 for an invoice, 381 for a credit note, 384 for a corrected invoice, 386 for a prepayment invoice, 389 for a self-billed invoice.
Where it happens
This code comes from EN 16931, the European e-invoicing standard. It concerns business term BT-3.
