BR-DE-26 — Corrected invoice without preceding reference (BG-3)

• Standard: XRechnung
• Severity: warning
• Business Terms: BT-3, BT-25

Meaning

When "Invoice type code" (BT-3) carries code 384 (Corrected invoice), the PRECEDING INVOICE REFERENCE group (BG-3) should appear at least once.

Possible causes

• BT-3 = 384, yet cac:BillingReference/cac:InvoiceDocumentReference is absent.

How to fix it

• Add cac:BillingReference/cac:InvoiceDocumentReference carrying the corrected invoice's number (BT-25).

Affected fields

• /ubl:Invoice/cbc:InvoiceTypeCode
• /ubl:Invoice/cac:BillingReference/cac:InvoiceDocumentReference
