Reference

BR-DEX-04 Party identifier scheme must use an ISO 6523 code

Any scheme identifier on a party identifier (Seller BT-29, Buyer BT-46, Payee BT-60) 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 (such as DIGA identifiers) for party identifiers.

Set the @schemeID on cac:PartyIdentification/cbc:ID to a valid ISO 6523 ICD value (for example 0088 for GLN). If you do not need Extension identifiers, the standard XRechnung CIUS profile avoids this rule.
