Which display shows the components directly used in a parent item and shows only a one-level relationship?

• A. Product structure tree
• B. Single-level bill of material
• C. Bill of materials
• D. Indented bill of materials

Answer: (B)

This item tests understanding of how BOM displays represent the depth of a product’s structure. The display that lists only the components directly used to build the parent item and shows just one level of relationship is the single-level bill of materials. It presents the immediate parts required per unit of the parent, with their quantities, and contains no subassemblies or deeper levels. This makes it ideal for quick material planning and inventory checks of the direct components needed to make the parent item. By contrast, a product structure tree shows the full hierarchical chain of assemblies and subassemblies, and an indented BOM presents multiple levels with indentation to reveal depth. So the single-level BOM is the format that matches a one-level, directly used-component view.
