Working with the SOA Manager 
You can use the SOA Manager to administer and configure service providers and consumer proxies for a local system.

Communication Between a Consumer Proxy and a Provider Proxy
Communication between the service consumer and the service is established between the consumer proxy’s logical port the provider proxy’s endpoint. To access a service endpoint, a service consumer with a runtime configuration sends a call through a logical port.
The logical port of the service consumer contains a reference to the unique address (URL) of the service’s endpoint on the provider system. The logical port also contains the authorization needed to call the service methods.
Note
A logical port can send a call to only one service endpoint. However, a service endpoint can be called through more than one logical port.
The service and proxy definitions that you want to configure are available as development objects in the back-end system.
You have Administrator authorization.
For more information, see: Authorizations
To configure a service provider:
Call the Object Navigator (transaction code SE80).
Choose Repository Browser.
Locate a service provider and double-click to display its properties.
To switch to Edit mode, choose
Choose .
The SOA Manager is started in a new browser window, displaying the properties of the service definition.
Alternatively, use the transaction code SOAMANAGER to start the SOA Manager, then search for a service definition.
Note
To set up the SOA Manager for local access, you do not need to perform any special steps.
