Where to write code for i_step =0

Question

Hi,
I have written code for variable i_step=0 in CMOD.
I am not able to test the code.
Could you pls tell us, how to test the code and when this code will be populated.
Where do i need to set break point , to see the code execution in debugging.
Thanks

You will write the logic using CMOD transaction only.You can set the break point the cmod code itself to check your code is working fine or not.
I_STEP = 0
The enhancement is not called from the variable screen. The call can come from the authorization check or from the Monitor. This is where you want to put the mod for populating the authorization object.
Check the sample code
case i_vnam.
  WHEN 'ZGMGRANT'.  "Query field name
    if i_step = 0.
BREAK-POINT
      clear wa_ETRANGE.
*     Gets all grants a user is able to see from ZTable,
*     which is populated elsewhere 
      select grant_nbr
        from ZGMUSERGRANTS
        into corresponding fields of table it_ZGMUSERGRANTS
       where UNAME eq sy-uname.
*     Populate Authorisation Object. In i_step 0
*     E_T_RANGE is used to populate the authorisation object
      loop at it_ZGMUSERGRANTS into wa_ZGMUSERGRANTS.
        wa_ETRANGE-sign = 'I'.
        wa_ETRANGE-opt = 'EQ'.
        CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
          EXPORTING
            INPUT         = wa_ZGMUSERGRANTS-grant_nbr
         IMPORTING
           OUTPUT        = wa_ZGMUSERGRANTS-grant_nbr.
        wa_ETRANGE-low  = wa_ZGMUSERGRANTS-grant_nbr.
        append wa_ETRANGE to E_T_RANGE.
      endloop.
    endif.
  ENDCASE.
