BR-FR-02_BT-25: Referenced invoice number format

What it means

In UBL, this checks cac:BillingReference/cac:InvoiceDocumentReference/cbc:ID under Invoice or CreditNote. The permitted letters are A-Z and a-z, the permitted digits are 0-9, and the listed symbols are plus (+), hyphen (-), underscore (_) and slash (/). The check prohibits all spaces. In CII, it checks the referenced invoice's ram:IssuerAssignedID in the same way.

Why it matters

This reference identifies the earlier invoice to which your invoice or credit note relates. Its format must follow this French rule while still identifying the correct document.

How to fix it

Compare the reported reference with the number on the earlier invoice. Correct transcription errors in cac:BillingReference/cac:InvoiceDocumentReference/cbc:ID for UBL or the referenced invoice's ram:IssuerAssignedID for CII, following the character and spacing conditions for that syntax. Do not remove or replace characters if that would make the reference differ from the actual invoice number. If the original number itself contains unsupported characters, ask your software supplier or e-invoicing platform how to represent the reference. Export the corrected file and check it again in Klarbon.

The rule as published

L'identifiant de facture référencée (cbc:ID) doit respecter le format autorisé : caractères alphanumériques et les symboles - + _ /. Il ne doit pas contenir uniquement des espaces, ni commencer ou se terminer par un espace, ni contenir d'espaces consécutifs. Valeur actuelle : " … ". Veuillez corriger le format de l'identifiant.

Where France CTC (CII) run it, the rule reads:

L'identifiant de facture référencée (ram:IssuerAssignedID) contient des caractères non autorisés. Valeur actuelle : " … ". Seuls les caractères alphanumériques et les symboles + - _ / sont autorisés, sans espaces.
