BR-FR-17_BT-123

Explanation

In French e-invoices, an attachment's description is a fixed code saying what it is: RIB (bank details), LISIBLE (readable copy of the invoice), FEUILLE_DE_STYLE, PJA, BORDEREAU_SUIVI, DOCUMENT_ANNEXE, BON_LIVRAISON (delivery note), BON_COMMANDE (purchase order), BORDEREAU_SUIVI_VALIDATION, ETAT_ACOMPTE, FACTURE_PAIEMENT_DIRECT or RECAPITULATIF_COTRAITANCE. Free text is not allowed there. The requirement comes from the French e-invoicing rules, not from EN 16931.

How to fix

Ask the seller for a corrected invoice in which every attachment carries one of these codes as its description. If none fits exactly, DOCUMENT_ANNEXE (other attachment) is the usual choice.
