Leaving FPM application in Portal..!

Hi Guys,

               I am using a FPM GAF config application in portal.

There is a popup window to confirm the completion and then to leave FPM application, I am using the following code.

** Raise the FPM close event

  DATA: lo_fpm TYPE REF TO if_fpm.

   lo_fpm = cl_fpm_factory=>get_instance( ).

  lo_fpm->raise_event_by_id( 'FPM_CLOSE' ).

This is actually closing the portal window. This is not what I want, rather a leaving the FPM application to portal home screen or the role screen where this iView belongs.

I tried   lo_fpm->raise_event_by_id( IF_FPM_CONSTANTS=>GC_EVENT-LEAVE_INITIAL_SCREEN ) with no success, because the popup screen is not part of  the FPM.

Thanks

Sam
