auto_awesome What this module does

AI-generated from the code · Odoo 12.0

Prevents cashiers from creating Point of Sale orders on a session that is no longer open. It checks the session state every few seconds and shows a blocking pop-up if the session was closed or is in closing control.

In Odoo Point of Sale, the front-end keeps working offline, so a cashier could keep selling on a session that has already been closed. This module adds a safety check.

  • On each Point of Sale configuration (pos.config), a new field "Frequency of Checking the State of the Session" lets you set how often the check runs, in seconds. It is shown in the Point of Sale settings form.
  • When the Point of Sale interface starts, it schedules a check at that frequency. The check asks the server for the current state of the session.
  • If the session is not opened, a blocking error pop-up appears with the session name and a message explaining that the window will be closed and a new session must be opened. The pop-up closes the Point of Sale window.
  • On the server side, when an order is sent to be processed (pos.order), the module refuses it if the related session is closed, raising the error "Unable to write an order in a closed Session".

The module touches the Point of Sale configuration screen and the order processing logic. It does not add new menus.

terminal Installation and usage

OCA documentation · Odoo 12.0

Configuration

Source · Odoo 12.0
  • Go to Point of Sale / Configuration / Point of Sales
  • Open a PoS Config and set a frequency for the check
  • Alternatively, if you let the value to 0, a lazy check will be done when trying to save the order. This setting can be interesting, if you have a poor connexion, because the check done regularly could generate a bad UX experience in that case.
