Use this dialog box to reschedule a work order. Rescheduling is necessary when the prerequisites for the work to be performed changes, for instance due to emerging work or changes in the resource situation or when there are resource constraints. A work order that is connected to a work order (WO) structure or project will not be rescheduled immediately since there are frequent multiple updates done to a WO structure or project and these updates need to be completed before the reschedule can take place.
