Hi Sathya,
You need to create a WSDL file in XMLSPY tool (You can use other tools available) manually and provide the operations and binders information manually for whatever operation you want and consume the WSDL as Provider in designer.
By this way you will expose only the selected API’s.
Also as @Rakesh mentioned you can either virtualize the service and edit the WSDL or edit the WSDL file directly and keep only selected operations.
