What it means
Among the invoiced object identifiers (BT-18) of the whole invoice, scheme AFL may appear once and scheme AVV may appear once. Your file has more than one of at least one of them. Identifiers on invoice lines are checked separately, by BR-FR-30_BT-128.
Why it matters
The French platform expects one value per scheme and cannot tell which duplicate is right, so it rejects the invoice.
How to fix it
In the invoice header, look at the invoiced object references and delete the duplicates. Keep the correct AFL identifier and the correct AVV identifier. If your software adds these references itself, check that it is not adding the same one twice.
The rule as published
Parmi les identifiants d’objets facturés (BT-18), les schémas d’identification "AFL" et "AVV" ne doivent être présents qu’une seule fois chacun. Actuellement : AFL = … occurrence(s), AVV = … occurrence(s). Veuillez supprimer les doublons pour respecter la règle. Business terms: BT-18
