File non conforme al formato (schema XSD)

What it means

The FatturaPA XML does not conform to the official AgID schema (Schema_del_file_xml_FatturaPA v1.2.x): a required element is missing, an element is in the wrong order, or a value does not match the type/pattern/enumeration the schema allows.

How to fix it

Read the schema-violation message that follows: it names the offending element. Fix the element order (the FatturaPA schema sequences are strict), add the missing mandatory element, or correct the value to match the allowed type/codelist. Re-validate against Schema_del_file_xml_FatturaPA_v1.2.2.xsd before re-submitting to the SdI.

Example

<!-- WRONG: PECDestinatario before ContattiTrasmittente --> ... <CodiceDestinatario>0000000</CodiceDestinatario><PECDestinatario>x@pec.it</PECDestinatario><ContattiTrasmittente/>  <!-- RIGHT --> <CodiceDestinatario>0000000</CodiceDestinatario><ContattiTrasmittente/><PECDestinatario>x@pec.it</PECDestinatario>
