I would like to configure OpenERP that when a sales order is confirmed, the warehouse and manufacturing employees are automatically notified to start building it. I would then like a notification that it is done. I do not want to have to go in and assign my workers to a particular task. It would seem the routing or the work order would automatically be sent to the department and the entire chain would happen automatically. Am I missing something?

I would even be happy with group level notifications, but it doens't seem to happen. Am I missing a module/app?
