Understanding the Visual Bill of Material
A bill of material (BOM) is a list of all the components and the quantities of each component required to manufacture a product. A BOM can contain other BOMs, as well as information about raw materials, subassemblies, and so on.
The Visual Bill of Material program (P30003X) enables you to view a BOM as a hierarchical diagram, and to expand and collapse levels of the hierarchy as needed. You can view details about each item in the BOM, and access many commonly used programs for working with bills of material.
