Northern Trail Outfitters (NTO) wants to track and report on individual tasksCompleted, including parts consumed...

The correct configuration is Work Order Line Items, each with its own Service Appointment. Each task must retain its own completion, inventory, pricing, and scheduling information. A Work Order Line Item provides the task record, and a child Service Appointment allows that task to be scheduled to the same or a different technician as required.

Good Work Order design also preserves the distinction between planned work and execution results. Products Required, requirements, and task structure should be established before service; Products Consumed, actual times, signatures, and completion statuses then record what actually happened in the field.

The alternatives address different parts of the Field Service model. Custom objects are unnecessary, and using Service Appointments as the parent of task records reverses the standard Field Service data model.

This approach keeps the implementation aligned with the standard Field Service data model and avoids unnecessary customization. Study Guide reference: Managing Work Orders — Work Order Line Items; child Service Appointments; task scheduling.
