Please tell some tactics to use Stored Procedures in OLEDB Source task.

Hi mates,
In OLEDB Source task, I have tried to use the Stored Procedures in the SQL source command. But the task is not producing the expected results in the SQL table. I have tried the same SP in SSMS. It was producing the results as expected. I am not aware of using the SP in OLEDB source command.
There must be some tactic to do this. Can anyone give some ideas as to how to handle the Stored Procedure in the OLEDB Source task?
Thank you.
