Hi Vimal,
I checked EHHSS_INC_REC_OIF_V3 component configuration and found that such confirmation pop-up is shown in case if if_ehhss_ui_inc_constants_c=>gc_evt_set_closed_root event is triggered. Try to trigger such event on enter of field location.
It looks like that you must add as parameter (/bofu/if_fbi_runtime_c=>sc_application_parameters-key) of this event root key of processing BO.
Kind regards, Aliaksandr.
