What does this mean?

If a buyer electronic address (BT-49) is given, it must have a scheme identifier (BT-49-1) stating what kind of address it is. The attribute schemeID is missing; CII also rejects an empty attribute, UBL only a missing one.

Typical causes

The buyer's electronic address, e.g. a German Leitweg-ID or an e-mail address, was given without a scheme.
CII: The first electronic address is checked; a scheme on a further address only is not sufficient.

How to fix the error

State the scheme code from the EAS code list for the electronic address, e.g. 0204 for a German Leitweg-ID, EM for an e-mail address or 0088 for a GLN.
CII: ram:BuyerTradeParty/ram:URIUniversalCommunication/ram:URIID/@schemeID, UBL: cac:AccountingCustomerParty/cac:Party/cbc:EndpointID/@schemeID.
Generate and validate the invoice again.

In E-Rechnungsfreund

In the invoice form ("Experte" view), section "Käufer (BG-7)" (buyer), select the appropriate scheme in the field "EAS-Schema der elektron. Adresse (BT-34-1/49-1)" (EAS scheme of the electronic address). If no scheme is selected, the address from "Elektronische Adresse (BT-34/49)" is output without a scheme.

Example

Wrong

<ram:BuyerTradeParty>
  ...
  <ram:URIUniversalCommunication>
    <ram:URIID>04011000-12345-34</ram:URIID>
  </ram:URIUniversalCommunication>
</ram:BuyerTradeParty>

Correct

<ram:BuyerTradeParty>
  ...
  <ram:URIUniversalCommunication>
    <ram:URIID schemeID="0204">04011000-12345-34</ram:URIID>
  </ram:URIUniversalCommunication>
</ram:BuyerTradeParty>
