Customer Exit var (basedOn 0P_KEYDT) ABAP error - Going into Debug mode

Question

Hello All,
I have created a BEX Query based on Infoset, so i couldnt use '0P_KEYDT' SAP Exit in a variable.
Instead i created a Z 'Customer exit' with the same code.
But when i execute query in RSRT, query is going into Debug mode.
InfoProviders are all active, when i remove the Z 'Customer Exit' from the query then query is running fine. So i see that the problem is with the Z 'Customer exit' code.
Here is the 0P_KEYDT code:
FUNCTION RSVAREXIT_0P_KEYDT.

endmethod. 
I could really appreciate your help!
Thanks in advance,

Hi DeeCh.
If you want to populate the value before the variabel screen input.then please follow below code
case i_vnam.
  when 'ZPKEYDT'.
  if i_step = 1.
    l_s_range-low  = sy-datum..
      l_s_range-sign = 'I'.
      l_s_range-opt = 'EQ'.
      APPEND l_s_range TO e_t_range.
      clear l_s_range.
          endif.
          endcase.
