Find the source field
cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cbc:PostalZone
Match namespace URI and element name, not a particular prefix spelling. The validator reports the full expanded-name source path when the published rule supplies a location.
Common causes
- Postcode was included inside the city string instead of cbc:PostalZone.
Invalid and corrected fragments
<cac:PostalAddress><cbc:CityName>Berlin</cbc:CityName></cac:PostalAddress>
<cac:PostalAddress><cbc:CityName>Berlin</cbc:CityName><cbc:PostalZone>10115</cbc:PostalZone></cac:PostalAddress>
Populate cbc:PostalZone (UBL) or ram:PostcodeCode (CII) in the seller postal address.
