Navigation between two Pages in Floor Plan Manager

Hi All,

I am looking to implement a development where I need to navigate between two pages on the click of a button and then come back again on clicking back button. I wanted to know the best way to achieve this.

Environment is OIF.

I did use the interface IF_FPM_OIF_CONF_EXIT and via method OVERRIDE_EVENT_OIF, I can manage to call the new screen. But this method has it's own shortcomings. Hence, wanted to know if there is a way to trigger a new page/ variant from the PROCESS_EVENT or GET_DATA methods of a feeder class.

Thanks in advance for any help in this regard.
