An allowance or charge base amount has no percentage
The percentage must be provided as soon as an allowance or charge base amount is.
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.

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.

Why this error happens
The reverse of PEPPOL-EN16931-R041. It often comes from a discount captured as a value, whose base was filled in “for information” without the matching percentage.
How to fix it
Fill in the percentage, or drop the base if the discount is a flat amount. Factlint computes the expected percentage and returns it in `suggested_value` — without ever writing it.
