Oracle Field Service (OFS)
Routing assigned an activity to the Field Resource to be performed at 9:00am when his shift starts at 12:00pm.
Routing can assign an activity to Field Resources and place it at a time before their working shift start if the resources activated their routes prior to the start of their shift. When the resources activate their routes it means that they are ready to work and available to take jobs.
To avoid this situation, the resources should only activate their routes when they are actually ready to work.
