ITA - Data competenza IVA e inversione contabile

This module is an automatic bridge between two Italian localisation features: the VAT settlement date and reverse charge self-invoices.

When a reverse charge is applied to a customer invoice, Odoo creates a related self-invoice. With this module installed, the VAT settlement date entered on the original customer invoice is copied onto that generated self-invoice, so both documents fall in the same VAT period.

• It works automatically in the background; no extra button or menu is added.
• The VAT settlement date field is shown on the journal entry form for customer invoices, customer receipts and customer credit notes, and is hidden for other document types.
• The date picker warns when a future date is chosen.
• It touches the account.move model and the journal entry form view.

Because the module is set to install automatically, it activates as soon as both the reverse charge and VAT settlement date modules are present. No new menus, reports or scheduled actions are added.
