As shown in FIG. 11, in this embodiment, after the preparation of the order data, if it becomes necessary to change the part 2 (50 pieces) to the part 9 due to a shortage of parts, etc., to calculate the required replacement quantity (40 pieces) of the replacement parts (part 9) required for the production quantity, and the arrangement identifier (slip number HA00000004) for the component for which the change was instructed, the replacement required quantity, and the replacement parts for the replacement parts Identifiers (“BHN0009” and “Part 9”) and/or replacement requirements data (order schedule data) including order identifiers, required quantities and component identifiers for each component other than the components for which change instructions have been issued Creating. As described above, in this embodiment, since the linking information is held based on the actually created order number, it is possible to replace the part while keeping the linking information. That is, conventionally, the parts configuration of a product was simply stored in association with master information, and there was a problem that if a substitute part was used during product manufacturing, it could not be managed. Even if it is necessary to temporarily change the parts configuration due to the above, since there is no need to change the configuration master 106a, it is possible to temporarily replace missing parts with substitutes and promptly place an order.

Then, as shown in FIG. 12, in this embodiment, when the user designates a hierarchical display instruction with the slip number SZ00000001 as the top after the replacement part requirement calculation process, the number of intermediate units 1 is 50. 40 parts 9 are displayed, and the product X is displayed at the top, and the part 2 may be highlighted. In this way, in the past, since the linkage was held based on the master information, it was not possible to inquire if a substitute product was used. Allows for inquiry.
