Understanding QAS_QRY_SERVICE
Services are used to logically group a set of service operations. The service QAS_QRY_SERVICE contains all of the service operations for QAS. When you publish a web service, a WSDL document is created containing all of the selected service operations as well as the endpoints based on the service configuration.
QAS_QRY_SERVICE is delivered as a restricted service. Only a user with the PeopleSoft Administrator role can make changes to the restricted state.
See Integration Broker: Restricting and Enabling Write Access to Service Definitions.
This diagram illustrates how a client application consumes the web service
The published web service is stored in the WSDL Repository. Client applications consume the WSDL by accessing the WSDL URL from the repository. The WSDL for QAS_QRY_SERVICE is delivered and updated with the appropriate WSDL Repository location whenever the target location is updated on the Service Configuration page (Select PeopleTools, Integration Broker, Configuration, Service Configuration).
