What does UBL-CR-183 mean? A UBL invoice should not include the AccountingSupplierParty Party PartyLegalEntity CorporateStockAmount

Why did my invoice fail UBL-CR-183?

This EN 16931 rule warns when the UBL element cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:CorporateStockAmount is present: the invoice should not include the seller's corporate stock (share capital) amount as a structured element. Share capital is not a structured field in EN 16931; where legally required (e.g. for some company forms) it is expressed inside the free-text additional legal information (BT-33, cbc:CompanyLegalForm). The element is not forbidden by UBL itself, but it lies outside the EN 16931 core invoice model, so remove it to keep the invoice fully conformant and interoperable.
