BR-08: The seller postal address 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 seller address group (BG-5) is absent. The standard requires the GROUP, even though only the country code inside it is truly mandatory.
How to fix it
Add SellerTradeParty/PostalTradeAddress, with at least the country code.
Where it happens
This code comes from EN 16931, the European e-invoicing standard. It concerns business term BG-5.
