Enterprise Service 
You use this action to connect to a services registry and search the services based on the following:
Classification
Physical systems
Service names
To use this action, you must configure the J2EE engine, on which SAP MII is running, to point to the services registry. For more information about this configuration, see Configuring a Central Services Registry in the SAP NetWeaver CE 7.1 EHP1 help at http://help.sap.com.
When you configure the action, you enter search criteria to find services and view the following details:
Details
Service Endpoints
The different implementations of the service that may be available
Classifications
Classifications associated with the service
Physical System
Details about the physical system that published the service on the service registry
The system passes the WSDL URL from the service to the Web Service action so you can select the interface and operation and configure the links in the Link Editor screen.
After you select a service on the initial configuration screen, you click Next to continue to the same screens used to configure the Web Service action.
