auto_awesome What this module does
AI-generated from the code · Odoo 16.0Adds extra security groups that control what a cashier is allowed to do inside the Point of Sale screen, such as giving discounts, changing prices, selling negative quantities, deleting orders or lines, opening several orders and taking payments.
This module adds seven new user groups (in the Usability category) that decide which buttons and actions are available to a cashier in the Point of Sale interface:
- Point of Sale - Negative Quantity: allows selling a negative quantity (returns).
- Point of Sale - Discount: allows setting a manual discount.
- Point of Sale - Unit Price Change: allows changing the unit price of a product.
- Point of Sale - Many Orders: allows working on several orders at the same time.
- Point of Sale - Delete Order: allows deleting a whole order.
- Point of Sale - Delete Order Line: allows deleting a line in an order.
- Point of Sale - Payment: allows taking the payment of an order.
On each Point of Sale configuration (pos.config), computed fields store the identifiers of these groups so they can be sent to the Point of Sale frontend. When a session is loaded, the user information sent to the screen (pos.session) is enriched with flags telling whether the connected cashier belongs to each group.
In the Point of Sale screen, the Pay button, the minus button, the backspace (delete line) button, the discount and price controls, and the button used to start a new order are disabled when the cashier does not have the matching group. Deleting an order is also blocked at the action level. No new menus or reports are added; the change is visible directly in the existing Point of Sale screens.
