After initiating the Event, a couple of things happen. For starters, the Event notification button will pop up in the lower left-hand corner of your desktop. This button alerts you that an Event you are subscribed to has occurred:

Event Notification Alert

To see details about the Event, we double-click on the alert button. Doing so opens the xTuple ERP Event Manager, as shown in the following screen:

Event Shown in Event Manager

As you can see in the example, the Event for the current user is displayed. If you are a manager with permission to view Event details pertaining to other users, you would have the ability to select another user on this screen. Looking at the details for our current user, we see the Warehouse where the Event occurred, the time and date of occurrence, the type of Event, and the associated Order number. To acknowledge receipt of the notification, we select the Acknowledge option from the right-click menu. Finally, to confirm the time and date of acknowledgement, we select the Show Acknowledged Events option, as shown in the following screen:

We have now followed a complete life cycle for the Event "WoQtyChanged." Apply the same techniques discussed in this example when subscribing to and tracking other system-defined Events.
