To determine which BOMs an object is used in, you need to start a "bottom-up" analysis of BOMs.

You can produce a where-used list for the following objects:

• Material (multi-level)
• Document (single-level)
• Class (single-level)

This section describes the where-used list for materials in detail. You can produce where-used lists for documents and classes in the same way.

A where-used list answers the question: Where is an object (for example, material) used, and in what quantity?

This question is especially important, for example, if objects (such as materials) are used in more than one context.

For example, you require this information to:

• Determine requirements for a specific material
• Select products that are affected by a change to an individual part
• Find assemblies that will be delayed if, for example, there is a delay in the delivery of a raw material

• Calculate the effect on the cost of a product if the price of a raw material rises
