The parent line identifier designates no line of the invoice

In the extended profile, every parent line identifier (EXT-FR-FE-162) must match the identifier (BT-126) of another line of the same invoice.

Only the issuer holds this value: Factlint reports it and never fabricates it. Test your invoice to find out whether it is affected.

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

An orphan sub-line attaches to nothing: the recipient can neither group it nor check it against its total. The typical case is a parent line deleted or renumbered after the sub-lines were generated. 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

Point the sub-line to a line that exists, or remove the reference. Factlint does not rebuild an invoice's hierarchy.

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.
