fatalEN 16931EN 16931 business ruleCIIUBLBT-1

An Invoice shall have an Invoice number (BT-1).

Why it fails

The Invoice number (BT-1) is missing.

How to fix it

Add BT-1 (UBL cbc:ID, CII rsm:ExchangedDocument/ram:ID). It must be unique within your sequence and non-empty; whitespace only does not count as a value.

What the validator checks

CII — context /rsm:CrossIndustryInvoice

normalize-space(rsm:ExchangedDocument/ram:ID) != ''

UBL — context /ubl:Invoice | /cn:CreditNote

normalize-space(cbc:ID) != ''
