Abstract: A multi-level system generates multiple custom work orders for the manufacture of an end item and lower-level configurable items comprising the end item. The system includes an order entry configuration for obtaining option values that define specifications for the end item and lower-level configurable items. An options storage within the system stores the option values and parameters for generating work order requirements for the end item and lower-level configurable items. The system further includes a manufacturing configuration which, after the order entry configuration processes the option values, generates the multiple custom work orders by interactively accessing the options storage.
