for i in 1.. V_count loop
     if((:desig is not null ) and (:new_date is not null) and (:emp_desig<>:desig) and (:new_date >=:emp_desig_date)) then
          :emp_desig :=:desig;
          :emp_grade:=:grade;
          :emp_desig_date:=:new_date;
          :emp_upd_by:=:global.usr;
          :emp_upd_on:=:system.current_datetime;
