Understanding Managing Services
Services are used to logically group a set of service operations.
For example, if you have a number of service operations that are related to customers, such as those pertaining to customer information, adding customers, updating customers, deleting customers, and so on, you can create a customer web service and then associate the related service operations with that service.
Warning! PeopleSoft delivers two services with PeopleSoft Integration Broker: IB_GENERIC and IB_UTILITY. These services are used internally by the system. Do not delete or modify these services.
Before you can provide or consume services in a PeopleSoft system, you must configure the system for handling services.Configuring the Integration System to Handle Services
