ITA - Ritenute d'acconto - Ordini di pagamento

This module is a small bridge between Italian withholding tax (ritenute d'acconto) and payment orders. It does not add any new menu or screen; it changes how the amount of a payment order line is calculated when the payment order is generated from invoice lines.

When a payment order line is prepared from an invoice line that carries a withholding tax amount, the module subtracts that withholding tax from the amount to be paid. In practice, the supplier is paid the net amount (Net To Pay) instead of the gross invoice amount, because the withholding tax portion is not included in the payment order.

The change applies to the account.move.line model through the preparation of payment line values used by the payment order feature. It only affects lines where a withholding tax amount is present; lines without withholding tax keep their normal amount.

No new fields, menus, reports, emails or scheduled actions are introduced by this module. It is installed automatically when both the Italian withholding tax module and the payment order module are present.
