What is the difference between an XSD error and a Business Rule error?
Short answer
The XSD error and the Business Rule error occur at different layers of e-invoice control. An XSD error means that the XML document does not correspond to the required technical schema. A Business Rule error means that the document may have the correct XML format
Technical problem
Bad element order, illegal element, wrong value type.
A logical problem
Totals or mandatory business data do not meet EN 16931/Peppol rules.
Not always a programmer
XSD is often handled by the developer or ERP. Business Rule may require an accountant.
Read rule id
The error code tells whether it is a scheme, a business rule or a local SK check.
