BR-FR-01_BT-1: Invoice number must be 35 characters or fewer

In short

Fatal: fails the selected checks.

BR-FR-01_BT-1 requires your invoice number (BT-1) in a French CII e-invoice to contain no more than 35 characters. If it is longer, shorten the number stored in rsm:ExchangedDocument/ram:ID and recheck the corrected file.

What it means

This rule checks the character count of your invoice number (BT-1) at rsm:CrossIndustryInvoice/rsm:ExchangedDocument/ram:ID. The limit is 35 characters, counting spaces and symbols as well as letters and digits.

Why it matters

The French CII rules set this length limit for the invoice number. A longer number fails this check.

How to fix it

Correct the invoice number in your source invoice so it contains no more than 35 characters, keeping it consistent with your invoice records. Generate the CII file again and check that rsm:ExchangedDocument/ram:ID contains the corrected number. Recheck the corrected file.

Once the file is corrected, check it again for free: Check an e-invoice
