Explanation

Lifecycle status messages (“cycle de vie”) are part of the French e-invoicing system: platforms and parties use them to report what happened to an invoice. Every message has to state which specification it follows. That statement is missing.

How to fix

Ask the sender of the status message for a corrected message. Status messages are usually generated automatically by the sender's platform or software, so the fault lies there, not in anything typed in.
