How to diffrentiate that control is from diffrent application in GAF Initial screen?

Hi All,

Following is my requirement :

I have created a Worklist ,if you click on Subject field it will take you to the respective material screen created in FPM GAF.Now this application also has Initial screen but i want to skip the initial screen.

i am already using the following methods in Override method.

      lo_fpm = cl_fpm_factory=>get_instance( ).

      lo_fpm->raise_event_by_id( if_fpm_constants=>gc_event-leave_initial_screen ).

but  then i am not able to diffrentiate that control is coming from Worklist or it's the new application opening because 'FPM_START' event is raised in both the cases.
