What does UBL-CR-199 mean? A UBL invoice should not include the AccountingSupplierParty AccountingContact

Why did my invoice fail UBL-CR-199?

This EN 16931 rule warns when the UBL element cac:AccountingSupplierParty/cac:AccountingContact is present: the invoice should not include an accounting contact on the supplier party wrapper. The core model allows only one seller contact (BG-6) under cac:Party/cac:Contact; an additional accounting-specific contact has no mapped business term. The element is not forbidden by UBL itself, but it lies outside the EN 16931 core invoice model, so remove it to keep the invoice fully conformant and interoperable.

Official rule text

A UBL invoice should not include the AccountingSupplierParty AccountingContact

Common causes

The finance department's contact was mapped to AccountingContact instead of cac:Party/cac:Contact
ERP exports multiple role-based contacts
Template copied from a full UBL 2.1 sample
