In any group category, you can arrange the groups in a high-to-low priority. A candidate member object is compared against the highest priority group first and becomes a member of the first group for which there is a criteria match.
The Priorities tab shows groups in the order of their priority, from highest to lowest.
To change the priority of a group:
In the Priorities tab, select the group for which you want to change the priority.
Click the up or down arrow to change its position relative to the other groups.
Click the Apply button to save your changes.
Click the Reconfigure toolbar button to make your changes take effect.
