What it means
In the EN 16931 profiles of Factur-X and ZUGFeRD, this rule checks schemeID on ram:BuyerTradeParty/ram:URIUniversalCommunication/ram:URIID. The scheme (BT-49-1) identifies the type of electronic address (BT-49). A non-empty scheme must be on the referenced code list. A missing or empty scheme passes this particular test. The address itself and its ability to receive invoices are not checked.
Why it matters
The scheme identifies how the electronic address is represented. Using a permitted code gives the address a consistent type in the structured data, but does not establish that it is a working delivery address.
How to fix it
Confirm the electronic address and its scheme with your buyer. Correct the scheme in your source invoice. In the XML, set schemeID on ram:BuyerTradeParty/ram:URIUniversalCommunication/ram:URIID to the matching permitted code. Use EM only when the value is an email address. Do not choose an unrelated code or remove an address that is required for your invoice. Export and recheck the file.
