Activity Scheduled Daily?
Under your activity settings, you have the option to select whether an activity can be scheduled daily. By selecting YES, you are letting the auto scheduler know this activity can be considered to be scheduled multiple times within the same week, although it is not a guarantee. If you need to guarantee a group will get a certain activity daily, utilize the guaranteed slots.
If you select NO for scheduled daily, the auto schedule will remove this activity as an option for further scheduling that week once a group has been scheduled for it. It does however still allow this group the opportunity to be scheduled for this activity again during future weeks.
