A generation horizon is the number of days before the maintenance plan start date that work orders are generated. A generation time frame is the number of days before the maintenance plan end date that work orders are generated. To ensure that work orders are generated within 14 days of inspection due date, both the generation horizon and the generation time frame should be set to 14 days. Associating a work type calledsite or a required skill called site visits to maintenance plans would not affect the timing of work order generation, but would affect the scheduling and assignment of service appointments.
