BR-DE-26
Corrected Invoice (384) Without Preceding Invoice Reference (BG-3)
What This Error Means
If the invoice type code BT-3 is 384 (corrected invoice), the group PRECEDING INVOICE REFERENCE (BG-3) should be present at least once, so the buyer knows which invoice is being corrected. In UBL this is cac:BillingReference/cac:InvoiceDocumentReference with the invoice number in cbc:ID (BT-25), in CII ram:InvoiceReferencedDocument. BR-DE-26 is a warning.
How to Fix It
Add cac:BillingReference after cac:OrderReference (before the parties) with the number of the original invoice in cbc:ID and, recommended, its issue date in cbc:IssueDate (BT-26).
<cac:BillingReference>
<cac:InvoiceDocumentReference>
<cbc:ID>RE-2026-4655</cbc:ID>
<cbc:IssueDate>2026-06-30</cbc:IssueDate>
</cac:InvoiceDocumentReference>
