This is a property of the file you received, so it cannot be corrected on your side without changing the document — ask the supplier to reissue it.

Worked example · UBL

schemeID on an endpoint is a code from the EAS list: a GLN is 0088, an email address is EM, a Leitweg-ID is 0204 — the scheme's name is not a code.

Fails this rule

<cbc:EndpointID schemeID="GLN">4012345000009</cbc:EndpointID>

Passes

<cbc:EndpointID schemeID="0088">4012345000009</cbc:EndpointID>
