Calling Function Module in IDT

Hi All,

I want to use a Function Module for to retrive some data by using IDT. I was able to get Function Module into the Datafoundation layer. But i do not know how to pass parameter of function module in IDT. I read some threads and it wont give me the answer that required.

How do i pass parameters and get the data that required?

Any help is highly appreciated.
