Italy FatturaPA and Sistema di Interscambio (SDI) Integration for SAP

Italy’s domestic e-invoicing obligation applies principally to VAT taxable persons resident or established in Italy; mere Italian VAT identification without establishment is not by itself sufficient. In-scope invoices are transmitted through the Sistema di Interscambio (SDI) in FatturaPA XML, subject to statutory exclusions. SAP teams need controlled invoice-data, validation, transmission, response and exception workflows.

The Compliance Challenge in Italy

Italy’s domestic e-invoicing obligation applies principally to VAT taxable persons resident or established in Italy; mere Italian VAT identification without establishment is not by itself sufficient. In-scope invoices are transmitted through SDI, subject to statutory exclusions.

Key facts SAP teams should plan around (as of July 2026):

• Cross-border data transmission: Since 1 July 2022, the separate periodic Esterometro return has been replaced by transaction-level data transmission through SDI. Outbound cross-border data uses the applicable ordinary sales document types and foreign-recipient routing; inbound purchases use TD17, TD18 or TD19 as applicable. TD28 is limited to the specific cases defined by the current AE guide and is not the standard foreign-purchase type.
• Technical specification: The current technical specification is version 1.9.1, usable from 15 May 2026. Pin SAP mapping and validation to the current AE schema, code lists and release notes.
• Scope keeps widening: flat-rate and micro businesses were phased in, and only narrow exceptions remain, notably a permanent ban (decree of June 2025) on sending B2C healthcare-service invoices through SDI for data-protection reasons.
• Archiving is part of the mandate: invoices exchanged through SDI must be preserved under Italy’s conservazione rules for 10 years, on both the issuer and recipient side.

Operationally, SDI response handling drives the workflow: delivery receipts, non-delivery notifications, and rejections each require different follow-up in SAP, and corrections use dedicated document types rather than free-form credit notes.

How S4FN Supports This in SAP

1. Reads relevant SAP invoice, tax, and master-data fields.
2. Maps required fields to the FatturaPA format, including TD document types and cross-border reporting cases.
3. Supports validation and error handling before transmission.
4. Prepares the SDI transmission workflow.
5. Tracks SDI receipts, non-delivery notifications, and rejections for follow-up.
