ABAP Help for customer exit

Question

Hi All, I need help with ABAP code for customer exit for formula variable. I have ZVKDATE as formula var from customer exit. user enters date in ZVKEYDT(this is selection type var). I have the below code, I debugged it the l_var_range-low get the date but when I append it to e_t_range the table doesn't gets the date. The report shows the ZVKDATE has empty demarcation. kindly help.
data l_var_range like rrrangeexit.
data: l_s_range type RSR_s_RANGESID.
data: w_day(2) type c,
      w_mth(2) type c,
      w_year(4) type c.
define append_range_table.
l_s_range-low = &1.
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
append l_s_range to e_t_range.
end-of-definition.
*Activities performed before selection screen pop-up window
if i_step = 2.
Calculate the current date based on system date
  case i_vnam.
    when 'ZVKDATE'.
      read table i_t_var_range into l_var_range
                        with key vnam = 'ZVKEYDAT'.
      l_s_range-sign = 'I'.
      l_s_range-opt = 'EQ'.
      w_day = l_var_range-low+6(2).
      w_mth = l_var_range-low+4(2).
      w_year = l_var_range-low(4).
      concatenate w_year w_mth w_day into l_var_range-low.
      append l_s_range to e_t_range.
  endcase.
endif.

Hi,
Check your code again. You are not appending l_var_range but l_s_range. Also I think the concatenate statement should contain l_s_range-low instead of l_var_range-low.
Hope this will help you.
