The vacation system provides OpsCenter users with the ability to manage their vacation schedules. The main component of the vacation system is the vacation calendar which displays the vacation schedules for all the users. The vacation calendar also displays non-workdays, holidays, and sick days. A user can add a vacation a couple different ways depending on how the vacation system is configured. One way to set up the vacation system is unrestricted access to adding vacation schedules. In this situation, any user can access a window where they can create a vacation schedule entry that immediately posts to the vacation calendar. A second way to configure the vacation system is to use a permission based approach. In this situation, only a predefined set of users can approve vacation schedules. When a user wants to add a vacation to the calendar, they must send a vacation request to one of the predefined users that can approve it. That user can approve or deny vacation requests sent to them. An approved vacation request is then automatically posted to the vacation calendar. (See the system controls for details on configuring the vacation system.) When the scheduled vacation time occurs, the user is automatically set to vacation status and a return date will be set as the next business day after the vacation ends. When the vacation time ends, the user is automatically returned to normal status.
