A line period ends after the invoicing period
`Invoice line period end date` (BT-135) must fall within the invoicing period declared in the header (BT-74).
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.

Why this error happens
The counterpart of PEPPOL-EN16931-R110, on the end of the period. It typically fires on a subscription billed in advance whose line covers the following month.
How to fix it
Widen the header period, or move the line onto a separate invoice. Factlint changes neither date.
