Purchase Invoice Create Security Group

This module lets you restrict the ability to generate vendor bills directly from a purchase order. It adds a new security group called 'Create Invoice in Purchases' and a company-level setting to turn the protection on or off.

Where it appears in Odoo: - In Purchase settings, a new checkbox 'Enable invoice creation from purchases protection group' is added under the invoicing section. - On the purchase order form, the 'Create Invoice' buttons are hidden for users who are not in the new group when the setting is active.

Business rules and automatic behaviour: - When the setting is enabled, any user not belonging to the 'Create Invoice in Purchases' group will not see the invoice creation buttons on purchase orders. - If such a user tries to create an invoice through another path, Odoo raises an access error telling them to ask the administrator for access. - By default, users with the standard accounting user role are automatically added to the new group, so they keep the ability to create invoices from purchases.

Areas touched: - Purchase orders (purchase.order) and their invoice creation action. - Company settings (res.company) and the general settings screen (res.config.settings). - Security groups and access rights.
