Universal Containers sells widgets with multiple components.

a parent Work Order with Asset-specific Work Order Line Items is the appropriate Field Service design. Work Order Line Items are the standard way to represent individual components, Assets, or tasks under one service engagement. Each line item can carry its own Asset, status, Work Type, products, skills, pricing, and appointment when needed.

Reusable configuration should be preferred over duplicating records or custom objects. Work Types can standardize duration, required skills, required products, and Knowledge, while the Work Order hierarchy and Work Order Line Item hierarchy are available when genuinely separate but related work must be represented.

The alternatives address different parts of the Field Service model. Separate parent Work Orders are only necessary when the work must have independent job lifecycles; Products Consumed records materials used, not the component-level work structure.

This approach keeps the implementation aligned with the standard Field Service data model and avoids unnecessary customization. Study Guide reference: Managing Work Orders — Work Orders; Work Order Line Items; Asset-level service tracking.
