Pass Table in a HTTP service

Hi SAP Gurus,

I'm new to ICF services handling. I'm trying to call a HTTP service from ABAP and using the class CL_HTTP_CLIENT and its interface to build request, send the request and receive the response. I'm able to pass a single structure but not a table parameter in the request. I'm using SET_FORM_FIELDS and even though I give the table, the request accepts only the latest entry. I used the program RSICFCLTST01 to test the URL. Its the same case here aswell. Can any one guide me on resolving this issue ?

Regards,
