What it means
In a UBL invoice or credit note, the seller (BG-4) has a postal address (BG-5) under cac:AccountingSupplierParty/cac:Party/cac:PostalAddress. This rule checks that this address has no cbc:PlotIdentification, a separate element for a plot or land parcel identifier.
Why it matters
This is a warning, so the file is still accepted. The EN 16931 address has no field for a plot, so the recipient's software normally ignores it. Fix it when the plot is needed to find your address, or when you want a file without warnings.
How to fix it
In your invoicing software, write the plot as part of an address line instead of a separate plot field, then export again. In the XML this is the street name (BT-35) or the additional address line (BT-36). If you build the XML yourself, delete cbc:PlotIdentification from cac:PostalAddress in the seller block.
