Reg : In GP interface call RFC for output structure

Hi ,

I am developing Webdynpro callable object through GP interface. In this task I have only output don't have input parameters. If i will click Test directly it will come output like this :

for ex: Name : Risha

EmpID : 1234

In getDescription() i created output structure and getting the structure.

For data i have to call RFC , RFC will fetch data for Loggedin user.

In GP interface how to call RFC and how to fetch the data for corresponding O/p structure.

I have to submit this data to Approvar. Please help me out.

Thanks in Advance,

Risha
