Final answer:
A direct scheduled work order needing material support can be completed without a required delivery date if necessary materials are already available, or if the work order is not material-dependent by a specific date. The Schedule of Work determines material availability and due dates, allowing for flexibility when materials are on hand or not urgent.
Step-by-step explanation:
A direct scheduled work order that requires material support can be completed without assigning a required delivery date when the materials necessary for completion are already available, or when the scheduled work order is not dependent on the availability of certain materials by a specific date. This situation generally applies to maintenance or repair operations where the necessary parts are in inventory or when the work can proceed with the materials currently on hand.
In the context of scheduling and managing work orders, it's important to consult the Schedule of Work to determine the date of availability and due date of materials. These dates typically guide the scheduling of work orders and the assignment of required delivery dates for materials. If there is no urgency for specific materials, or if substitutable materials are present, the work order can proceed with whatever materials are available at the time.
