BR-DEX-06 Item standard identifier scheme must use an ISO 6523 code

Any scheme identifier on the Item standard identifier (BT-157) 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 enable additional ISO 6523 item scheme codes (such as DIGA identifiers).

Solution

Set the @schemeID on cac:Item/cac:StandardItemIdentification/cbc:ID to a valid ISO 6523 ICD value (for example 0160 for GTIN). If you do not need Extension item schemes such as DIGA codes, the standard XRechnung CIUS profile avoids this rule.
