Default a value based on the selection in the pop up

Question

Hi Experts,
My requirement goes like this:
We have a custom pop-up to display plant fields for a component at the item level. If the user selects the plant in the pop-up, then the plant should get defaulted at the item level plant field. The plant field is also a custom field.
While creating the pop-up component, the binding has already been established between the two components.
My question is:
The pop-up component is different from the item view component. SO how to capture the event from the pop-up and code it to default the plant at the item level. How the code will be to call the value of one component from another.
How to default the plant value at the item block.
Thanks,
Sangeeta.

Sangeetha,
Incase of pop ups, we need to specify a CLOSE EVENT HANDLER at the
very same place where we call the pop up.
gref_popup = me->comp_controller->window_manager->create_popup(
                      iv_interface_view_name = 'xxx/MainWindow'
                         iv_usage_name          = 'Cuxxxx'
                         iv_title = lv_popup_title ). 
    gref_ppg_popup->set_display_mode( if_bsp_wd_popup=>c_display_mode_surrounded ).
  ENDIF.
* Set the callback event on the imported controller
  gref_ppg_popup->set_on_close_event(  iv_view = me
                                      iv_event_name = 'POP_CLOSED' ).
In this event handler(it will be created in the source component itself) , you need to capture the outbound plug information and the data on the pop up
ASSIGN me->context->('AGREEMENT') TO <pointer>.           "#EC NOTEXT
  lr_target_node ?= <pointer>.
  IF sy-subrc NE 0.
    RAISE EXCEPTION TYPE cx_bsp_wd_incorrect_implement.
  ENDIF.
  CHECK lr_target_node IS BOUND.
  IF   account_popup IS BOUND.
* get the result (list) from the search
    lv_fired_outbound =   gref_popup->get_fired_outbound_plug( ).
    CHECK lv_fired_outbound IS NOT INITIAL.
    lr_node =   gref_popup->get_context_node( 'PARTNER' )."#EC NOTEXT
    You can refer to any standard UI F4 value help and understand the logic behind.
