Retrieving the fnd_form_function.function_id for the current login

Hi,

Can anyone let me know how to fetch the current responsibility(resp_id) and the form function(function_id) for a particular session from a PL/SQL code ?

Scenario:

-> User logs into Applications

-> Clicks on Responsibility and a form function(OA PAGE)

-> does some ACTIONS on that OA PAGE

I need to fetch this responsibility details and also the form function details from a PL/SQL code that triggers during the above action.

Regards,

Pramod
