What does UBL-CR-353 mean? A UBL invoice should not include the Delivery DeliveryLocation CountrySubentity

Why did my invoice fail UBL-CR-353?

The invoice should not contain the CountrySubentity element directly on DeliveryLocation (cac:Delivery/cac:DeliveryLocation/cbc:CountrySubentity). In EN 16931 the country subdivision of the deliver-to address (BT-79) belongs inside the delivery address (cac:DeliveryLocation/cac:Address/cbc:CountrySubentity), not on the location itself.

Official rule text

A UBL invoice should not include the Delivery DeliveryLocation CountrySubentity

Common causes

The province/state is placed on the Location element instead of inside its Address child
A flat address record is mapped onto Location-level fields

How do I fix it?

<cac:DeliveryLocation>
  <cac:Address>
    <cbc:CityName>Maribor</cbc:CityName>
    <cbc:CountrySubentity>Podravska</cbc:CountrySubentity>
    <cac:Country><cbc:IdentificationCode>SI</cbc:IdentificationCode></cac:Country>
  </cac:Address>
</cac:DeliveryLocation>
<!-- CountrySubentity (BT-79) goes inside cac:Address -->
