Customizing a Bill of Materials
A Bill of Materials (BOM) is a product structure report that identifies the items required to assemble a product. Currently, the BOM report includes only items from a part structure. Two types of BOMs are supported.
A BOM Hierarchy report shows the quantity and unit attributes of the "usage" associations and visually indicates the hierarchical levels.
A Parts List report is a list of all of the components (that is, parts that do not use other parts) in the part structure hierarchy. It uses information in the "usage" associations to determine the quantity of each component. Basically, it answers the question "When a part assembly is completely disassembled, what parts and how many of each do I have?".
Both of these reports are defined to be generated as an HTML page optimized for printing from a Web browser.
