An allowance or charge percentage has no base amount
The base amount must be provided as soon as an allowance or charge percentage 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.
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
A percentage with no base cannot be verified: the recipient cannot recompute the amount, and the invoice's arithmetic stops being checkable line by line. It is the counterpart of PEPPOL-EN16931-R042, which handles the reverse case.
How to fix it
Fill in the base amount in the system producing the invoice. When the amount and the percentage are present, Factlint computes the base and returns it in `suggested_value` — without ever writing it.
