Hi Srikanth,

First create the proxy like following:

Before doing this you need to have WSDL file for your webservice. Or the URL.

Go to Se80, select repository browser, and from the drop down select Package option.

There create your package or you can use exsisting package. Then right click on it,, select create enter prise service. there select "service consumer". then select the file from local system or url etc.Once you give all these details proxy will be created based on the WSDL file which you have uploaded.

Then you have to create Logical Port.

Go to tcode" SOAManager" then go to business administration->webservice administration -> search by consumer proxy->select your proxy(apply selection button) -> go to configuration-> create logical port->Give some name for your service as well as port name( which you have to use in your program), then again upload your WSDL file. Finally port will be created.

Afterwards you can use the operations from wsdl file (generated Methods in SAP) in your ABAP program. You can see all the methods which are generated in your proxy. Go to your package, you can find your proxy under client proxies, in that you can find all the methods and parameters etc. which SAP generates based on WSDL file which you upload.

Hope it solves your problem.
