If the user would like to discard any changes they have made using the edit mode and let the application generate a schedule based on the most updated criteria, the user will need to erase the schedule.  This can be done using the 'Erase the Schedule' button on the View Schedule window shown in Figure 2.5.1-2.  Upon clicking this button a dialog as shown in Figure 2.5.4-1 will be shown.  If 'Yes' is chosen in this dialog the user will be returned to an empty View Schedule window as in Figure 2.5.1-1.
