The invoice carries no VAT breakdown
An invoice must contain at least one VAT breakdown group (BG-23), even when it carries no tax at all.
A financial field: the expected value is computed and offered, never written into the document — the correction is the issuer's to make. Test your invoice to find out whether it is affected.
The message your validator prints
Copied verbatim from the sealed artefact: this is the exact sentence the check prints when this rule fails.
[BR-CO-18]-An Invoice shall at least have one VAT breakdown group (BG-23).

Test your file with this error in mind
Upload the invoice involved: the report will say whether this code appears, where it appears in the document, and whether Factlint can only report it or also fix it.
To automate this check in an ERP flow, call the validation API and link every returned code to its public page.
Why this error happens
The case comes up almost exclusively on invoices without VAT — reverse charge, exemption, small-business relief. The issuer concludes there is nothing to break down, whereas the standard expects precisely a zero-rate breakdown carrying the exemption reason.
How to fix it
Add the BG-23 group matching the invoice's regime. Its taxable base and tax amount are financial fields: Factlint computes them and returns them in `suggested_value`, without ever writing them.
