BR-02 — E-Invoice Validation Rule & Fix

Fixture ID: empty · XPath: /ubl:Invoice/cbc:ID

1. Why This Rule Triggers (Diagnostic Message)

An invoice must have an invoice number (BT-1). It is the identifier the buyer, your accounts-receivable records and the tax authority all use to refer to this one document, so it must be unique within your numbering sequence.

2. How to Fix BR-02

Set invoiceNumber to your next sequential invoice identifier. Do not reuse a number, even for a document you later cancel — issue a credit note instead.

3. Valid Code / Payload Example

"invoiceNumber": "2026-000142"
