By default, DayBack allows you to assign multiple resources to an event. This app action ensures that an event can only belong to a single resource at any given time.
Resource Scheduling

This On Field Change action ensures that only the last-selected resource is assigned to the event. This will prevent DayBack’s default multi-resource assignment for a particular calendar source. This action can be modified in a variety of ways to only restrict resource assignments for particular statuses, calendars, or based on other event-level information.
