ITA - Registri IVA con Reverse Charge

This module is an automatic bridge between the Italian VAT registers and the reverse charge features. It does not add new menus or screens; it changes what is printed in the existing VAT register report.

When a VAT register is printed, entries coming from supplier self-invoices (autofatture passive) normally show the company as the counterpart. With this module, the report looks up the original purchase invoice linked to the self-invoice and prints the real supplier's name instead.

• For supplier self-invoices, the partner shown in the register becomes the supplier of the original purchase invoice.
• If the self-invoice has no reference of its own, the report uses the reference of the original purchase invoice.
• For customer self-invoices, the report also shows the original supplier and a reference combining the original document and the self-invoice, but only when that supplier is different from the partner already shown.

These changes rely on the links between self-invoices and their original purchase invoices provided by the reverse charge module. The module installs automatically when both Italian VAT registers and reverse charge are present, and it only affects the VAT register report template.
