Reference

BR-DEX-05 Legal registration identifier scheme must use an ISO 6523 code

Any scheme identifier on a legal registration identifier (Seller BT-30, Buyer BT-47, Payee BT-61) must be coded using one of the ISO 6523 ICD code list entries.

Problem Description

ERROR

XRechnung extension rule (KoSIT, BR-DEX) · XRechnung 3.0

Context and Significance

This XRechnung Extension rule fires only in the Extension scenario, which relaxes the core severity to permit additional ISO 6523 scheme codes for legal registration identifiers.

Solution

Set the @schemeID on cac:PartyLegalEntity/cbc:CompanyID to a valid ISO 6523 ICD value. If you do not need Extension registration schemes, the standard XRechnung CIUS profile avoids this rule.
