An invoice line net amount does not match its own calculation
`Invoice line net amount` (BT-131) must equal quantity × (net price ÷ base quantity), plus the line's charges and minus its allowances.
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.
Invoice line net amount MUST equal (Invoiced quantity * (Item net price/item price base quantity) + Sum of invoice line charge amount - sum of invoice line allowance amount

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
This is the line-by-line equivalent of `BR-CO-15`, and the same cause recurs: rounding applied to the unit price instead of the line total. The check tolerates two cents (fifty forints in HUF), which absorbs honest rounding and leaves genuine gaps visible.
How to fix it
Fix the calculation in the system that produced the invoice. Factlint computes the expected value and returns it in `suggested_value`, but never writes an amount.
Severity returned by the rule set
The package classifies it as `warning` where the equivalent header check is blocking. An in-scope warning still rules out a “compliant” verdict — at best the invoice comes out as `needs_input`.
