Cause
The seller's tax identification is missing or was specified with an incorrect SchemeID attribute. Common mistake: the SchemeID attribute is missing or misspelled.
Fix
Add either a tax number (SchemeID='FC') or a VAT ID (SchemeID='VA') in the seller section. Both can be provided. Tax number format: 13 digits without slashes (e.g. '1234567890123').
<cbc:ID>1234567890123</cbc:ID>
<!-- Tax number: --> <cbc:ID schemeID="FC">1234567890123</cbc:ID> <!-- OR VAT ID: --> <cbc:ID schemeID="VA">DE123456789</cbc:ID>
