cvc-complex-type.2.4.axsdBLOCKEDInvoice XML structure does not match the required schema
Your invoice file has a structural problem — required data elements are missing, in the wrong position, or unexpected elements are present. This is an XML Schema validation error, which means the basic structure of the file does not conform to the e-invoicing standard (UBL 2.1 or CII D16B). This is different from a business rule error: business rules check whether the data makes sense, while this error means the file format itself is wrong.
