An extended parts table 13 contains information specifying relevant lower level parts or "descendants" for each "parent" part and for each of the relevant lower level parts. The prime cost of a product is calculated based on the extended parts table 13, an item master table containing the purchase unit cost of parts D, E, F and a processing cost master table containing the processing cost of the parts D, E, F. As this eliminates the need for a hierarchical process of calculating the prime cost of a parent part, the processing speed is improved, no complicated application need be developed, and the table need not be updated during run time. |
