Because a SOAP service is created from a published WSDL document, you cannot add or delete service operations. You can only expose or hide an operation.
To hide or show a SOAP service operation:
Open the SOAP service that you want to edit using the SOAP service editor.
Select the Service Interface tab.
Choose from the following:
Expose a service operation. Right-click the operation, and select Set Visible from the context menu.
Hide a service operation. Right-click the operation, and select Set Invisible from the context menu.
