Web Service - Calling w/o input

Friends,

I imported a SAP wsdl in to LN and it generated the classes for me.

Questions:

When I try to make a minor modification to the generated code - it does not take it. Specifically - it has generated a SUB code with in a class declaration. I want to change it to a function to return a value.

I am trying to call an operation (in WSDL terms) that does not need an input parameter, but returns a value. It is called ‘RequestGuid’. It is in the form of a request/response - where there are no parameters for a request, but returns a value.

Let me know if you have pointers ?

Thanks
