BR-FR-09_EXT-FR-FE-06: Check the buyer's agent identifiers

In short

Fatal: fails the selected checks.

BR-FR-09_EXT-FR-FE-06 means the buyer's agent has a SIRET that does not contain 14 digits or does not start with that agent's SIREN. Check and correct the agent's identifiers.

What it means

When you supply a SIRET for the buyer's agent in EXT-FR-FE-06, this rule checks its length and agreement with the agent's SIREN. In UBL, this is cac:AgentParty under the buyer's cac:Party. The first selected SIRET must contain 14 digits and begin with the associated SIREN. No SIRET means this particular check passes.

Why it matters

The agent's SIRET and SIREN need to identify an establishment and company belonging together, rather than different organisations.

How to fix it

Check the buyer's agent details in the invoice, not the buyer's own identifiers. Compare the agent's SIRET and SIREN with that agent's confirmed registration details and correct the inaccurate number. Remove the agent details only if they were included in error. Generate the file again and recheck it.
