Hi Richa
The thing that you mentioned did not work as none of the view configurations have "NO_EMP_FILTER" as this field is present in the "available fields" pane ..This possibility has already been checked...Anyhow "cl_crm_uiu_bp_partner_popup=>account_f4_no_emp_filter( ir_popup = gr_bpsearchpopup ). " this breakthrough suggested by you helped me resolving the issue...Thankyou somuch...i have redefined the Outbound Plug"TOPARTNERSEARCH" and did the necessary coding and my issue is solved... 
please find the screen shots for the solution
