Decomposition rules specify the conditions in which Oracle Communications Order and Service Management (OSM) decomposes one or more order components into another order component. OSM evaluates every order item in the source order component against the conditions that you define for the decomposition rule. If an order item passes all specified conditions, OSM includes the order item in the target order component.
You can use decomposition rules when the fulfillment pattern associated with the order item is insufficient to determine whether additional order components are necessary. Decomposition rules are more flexible than fulfillment patterns, as they enable you to define XQuery rules to examine order item property values.
When modeling decomposition rules, refer to the following topics:
