Re: What is the need of creating & Consuming the web services ?

The following example is for a web service that accepts an HTTP GET with a three-parameter query string.  If you want to consume a SOAP web service, put the WSDL document in the generator in SE80 to build a proxy function.

DATA: webclient TYPE REF TO if_http_client,

      results TYPE string.

cl_http_client=>create(

  EXPORTING host = 'mydotnetserver.com'

  IMPORTING client = webclient ).

webclient->request->set_method(

  if_http_request=>co_request_method_get ).

cl_http_utility=>set_request_uri(

  request = webclient->request

  uri = '?param1=value1&param2=value2&param3=value3' ).

webclient->send( ).

webclient->receive( ).

results = webclient->response->get_cdata( ).

* Now you can parse the results

webclient->close( ).

You will most likely need to build a dynamic uri, so make sure and escape your parameter values using cl_http_utility=>if_http_utility~escape_url( ).  I hope this helps.  Let me know if you have any questions!

Best,
