An allowance or charge amount does not match its base amount and percentage
When an allowance or charge carries both a base amount and a percentage, its amount must equal base × percentage ÷ 100.
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.
Allowance/charge amount must equal base amount * percentage/100 if base amount and percentage exists

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 check tolerates a two-cent gap (fifty forints in HUF): what triggers it is therefore not rounding but a percentage changed without recomputing the amount, or the reverse. The usual source is a negotiated discount captured as an amount and then back-documented as a percentage.
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.
