How to setup Italian XML AR Invoice in CMK
I have implemented the CMK functionality for Electronic-Invoicing process by sending the XML file of AR invoices. I have defined the trading partner and then the provider to whom to send the XML file. The process was executed correctly, but the XML format does not comply with the requirements set by Italian law.
In the setup, I indicated "UBL_2.1_INVOICE_OUT" as the collaboration message definition. What do I need to do to obtain an output that aligns with the schema required by Italian law?
