Publishing Service Endpoints Implicitly 
Service definitions are published implicitly together with endpoints in the Services Registry. When service endpoints are created, updated, or deleted in the back-end system, information about the service endpoints is published implicitly to the Services Registry in accordance with the active publishing rules.
Note
When information is published implicitly, you will not be notified of the changes. You can check the Services Registry to find out which entities have been added.
Prerequisites
A connection to the Services Registry has already been created and configured. One connection is designated as the primary Services Registry in the ABAP back-end system.

From the SOA Manager main screen, go to the Application and Scenario Communication tab.
