BR-FR-31_BT-21: Use only one BAR note on the invoice

In short

Fatal: fails the selected checks.

BR-FR-31_BT-21 means the CII invoice has more than one note with subject code BAR that gives a category (B2B, B2BINT, B2C, OUTOFSCOPE or ARCHIVEONLY). Fix it by keeping one BAR note with the right category and removing the others.

What it means

A note in the document header of a CII file (BG-1) has a subject code (BT-21) and a text (BT-22). Notes with subject code BAR carry one of these texts: B2B, B2BINT, B2C, OUTOFSCOPE or ARCHIVEONLY. The rule allows one such note at most, so two BAR notes fail even when they say the same thing. This rule applies to CII files only; for UBL files the same check is BR-FR-30_BT-21.

Why it matters

The category in the BAR note tells the platform what kind of invoice it is dealing with. With two categories it cannot tell which one you mean, so it rejects the invoice.

How to fix it

Open the notes of the invoice in your software and look for those with the subject BAR. Keep the one that fits the sale and delete the others. If you did not mean to set a category at all, remove the BAR note.

The rule as published

Lorsque plusieurs notes ont le code sujet « BAR » (BT-21), Il ne peut y avoir qu'une seule valeur associée (BT-22, contenu de la note) parmi l’une des suivantes : B2B, B2BINT, B2C, OUTOFSCOPE, ARCHIVEONLY. Valeur fournie : " … " , Nombre de valeurs présentes (pas plus de 1) : … "/>". Veuillez corriger la valeur ou retirer le code sujet « BAR ».

Business terms: BT-21, BT-22
