Hi Manjunatha,
The generation of consumer proxies for multi-operation webservices using wsdl is unfortunately not supported from ABAP (including 7.40).
There is a way around it modifying the wsdl locally to only contain the operation that you want to trigger, and then later on once the proxy is generated manually change the transformation generated.
hopefully this gives you enough hints to find the details here in SCN.
regards
Sven
