What it means
The test counts ram:URIUniversalCommunication children of ram:InvoicerTradeParty. Zero or one passes; two or more fail. It counts communication blocks, not the address elements inside them.
Why it matters
The Extended profile provides one optional electronic address block for the invoicer.
How to fix it
Check the invoicer's electronic address in your invoicing software or XML export. Keep the ram:URIUniversalCommunication block for the intended address and remove extra blocks from ram:InvoicerTradeParty. Export the corrected file and check it again.
