What it means
This rule checks the buyer's legal entity block in a UBL invoice or credit note (cac:AccountingCustomerParty, cac:Party, cac:PartyLegalEntity). It must not contain cac:ShareholderParty, a nested party description for someone who holds shares in the buyer's company.
Why it matters
The rule excludes shareholder party blocks from the buyer's legal entity details. The check applies regardless of which shareholder the block describes.
How to fix it
Configure your UBL export to omit shareholder party blocks from the buyer's legal entity details. If the export cannot do that, ask your software supplier to change it. If you edit or generate the XML, remove every cac:ShareholderParty from cac:AccountingCustomerParty/cac:Party/cac:PartyLegalEntity. Recheck the file in Klarbon.
