BR-16 At least one invoice line is required

An invoice shall have at least one Invoice line (BG-25) describing a billed item, service or charge.

This is an EN 16931 core rule. An invoice without lines cannot show what is billed; even an invoice for a single lump sum needs at least one line. The UBL schema already requires cac:InvoiceLine, so BR-16 is mainly reported for CII invoices, typically when a summary invoice is exported with totals only.

Solution

Include at least one cac:InvoiceLine element with its identifier, quantity, price and net amount.
