What it means
In UBL, the check compares the number of schemeID attributes on the buyer's cac:PartyIdentification/cbc:ID elements with the number of distinct scheme values. A repeated scheme fails even when the identifier values differ. Identifiers without schemeID are not counted here; BR-FR-CO-10_BT-46-1 checks for missing attributes.
Why it matters
Keeping one buyer identifier per scheme gives each scheme a single identifier value for your recipient to use.
How to fix it
Compare the buyer identifiers and their scheme codes. Remove duplicate entries. If different identifiers genuinely use the same scheme, keep the one that should identify the buyer on this invoice. Change a scheme code only when it is incorrect for that identifier. Check the corrected file again.
