Generating a Consumer Proxy 
A consumer proxy is used to implement the enterprise service consumer.
You can generate a consumer proxy in the following ways.
Note
You need to know the URL of the WSDL document for the provider proxy.
Start the Object Navigator (transaction code SE80).
In the Repository Browser, right-click over the service provider to open the context menu.
Choose Create to start the wizard.
Select Service Consumer and Continue.
Select URL/HTTP destination and Continue.
Specify the URL of the WSDL document for the provider proxy.
You may be prompted to supply a host name, a port number, and your user.
Save and activate the consumer proxy.
You can generate a consumer proxy from the outbound service interface in the Enterprise Services Repository.
Start the Enterprise Services Browser (transaction code SPROXY).
Expand the nodes of the software component version and the namespace and select the outbound service interface.
Open the context menu and choose Create proxy.
A wizard prompts you through the steps to create a proxy. You need to specify a package, a prefix for the repository object names, and a transport request.
Check the information displayed in the External view and Internal view tabs. Here, you can see the operations and methods, and the corresponding ABAP message types and data types.
Save and activate the consumer proxy.
