Resource Scheduling Optimization (RSO) is an add-on capability for the Dynamics 365 for Field Service application that enables you to automatically schedule work orders for the most appropriate resources by optimizing bookings for the shortest travel time, available work hours, and many other constraints.

1. This add-on evaluates routes and automatically schedules bookable records to minimize travel time and maximize working hours and more based on your configured objectives, such as “minimize travel time” and “maximize working hours.”

2. This is not available in Trial Instances. You need to purchase an RSO Add-on, and its cost is $30/user/month. Also, you should have at least one purchased D365 Enterprise Edition license.
