A DETAIL line has no invoiced quantity
In the extended profile, a line of subtype DETAIL — or without a subtype — must carry an invoiced quantity (BT-129).
Only the issuer holds this value: Factlint reports it and never fabricates it. 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-FREXT-22]-Each Invoice line (BG-25) shall have an Invoiced quantity (BT-129), if the "Subtype of invoice line item" (EXT-FR-FE-163 / BT-X-8) has the value "DETAIL" or is not specified..

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 European standard requires a quantity on every line; the extended profile exempts structural lines and carries the requirement over to invoicing ones. A DETAIL line without a quantity has no verifiable unit price. It only applies to documents that declare the EXTENDED-CTC-FR profile — the profile sheet replaces the CEN package and adds its own rules for hierarchical lines.
How to fix it
Fill in the quantity, or give the line the GROUP subtype if it only structures. Factlint does not guess a quantity.
Severity returned by the rule set
Blocking since 1 September 2026: the current base, `fr-2026-09`, seals the FNFE 1.4.0.03 artefact in fatal mode, and it is the one the pinned engine applies by default. An invoice issued in August 2026 is judged against `fr-2026-08`, where the same rule comes out as a warning — which already rules out a “compliant” verdict. The API returns the severity of the rule set pinned for the judged invoice.
