Hi Tapas,
you can call the pop up as below where you need to have component interface but not the component usage.
lr_popup ?= me->comp_controller->window_manager->create_popup(
iv_interface_view_name = 'Your interface window'
iv_usage_name = if_bsp_wd_window_manager=>co_own_window
iv_title = lv_title ).
