The Appointment Scheduling Practice Preferences enable you to set options and default information for the appointment book for your practice and all related service locations. You can also enable interval overrides for the practice.
CAUTION:
If the interval overrides is enabled and you later want to disable it, changing the resource's time interval deletes all scheduling data currently in place for the resource. This includes: member classes, appointment conflict checking data, appointment search ahead data, appointment wait lists, default resource assignments, event duration overrides, template assignments, and template exceptions.
