BR-FR-DEC-01_BT-131: Invalid format for a line amount excluding VAT

In short

Fatal: fails the selected checks.

BR-FR-DEC-01_BT-131 means the amount excluding VAT on an invoice or credit note line (BT-131) has an invalid number format. Use at most two decimal places, a dot for decimals and at most 19 characters excluding the dot. A leading minus sign is allowed and counts towards the character limit.

What it means

BT-131 is the line amount excluding VAT, after line discounts and including line charges. In UBL, the checked element is cbc:LineExtensionAmount within cac:InvoiceLine or cac:CreditNoteLine; CII checks the corresponding field. This rule checks the number format rather than the line calculation.

Why it matters

Software adds the line amounts to obtain the sum of line amounts, so it needs to read each one as a number.

How to fix it

Find the affected invoice or credit note line and correct BT-131, not its unit price. If the calculation produces excess decimal places, round the line amount to no more than two decimal places. Use a dot, remove grouping separators and currency symbols, check the character limit and recheck the file.
