Application specific button on FPM toolbar to call action triggered in view

Question

Hello,
In the content area of my FPM is an ALV with some buttons, e.g. clicking one of the button opens up certain ALV column for editing (for simplicity, I omit the details besides simply enable the columns).
With FPM, I want the button to be placed in the toolbar as a application specific button. How do I achieve the same functionality e.g. from PROCESS_EVENT method calling an action (to open up certain ALV column for editing) via the application specific button placed on the toolbar communicating with the action/method found in the view controller ? Thank you.

Hi Arvind,
I tried as follows :
- Create an event in the component controller, say 'MA'
- Within PROCESS_EVENT, raise the event as follows :
  data : lo_fpm type ref to if_fpm,
         lo_event type ref to cl_fpm_event.
  create object lo_event
     exporting
        iv_event_id = 'MA'.
   lo_fpm = cl_fpm_factory=>get_instance( ).
   lo_fpm->raise_event( io_event = lo_event ).
- In the view controller, create an event handler which subscribe to the event, MA of the component controller.
However, the code in the event handler is never executed despite the event being raised. Not sure how FPM event flow works here.
Can anyone advise ? Thank you.
