BR-07: The buyer name is missing
This code shows up when an electronic invoice is validated. Here is what it means, why it fires, and what to change in the file.
Why this code appears
The buyer has no name (BT-44). Like the seller's, it is a mandatory particular: without it the invoice does not say who it is addressed to, and no accounting reconciliation is possible.
How to fix it
Fill BuyerTradeParty/Name. For a public body, use the name of the legal entity, not that of the department.
Where it happens
This code comes from EN 16931, the European e-invoicing standard. It concerns business term BT-44.
