Query Selection screen field validatoin

Question

I am testing a query using the RSRT2 transaction and have a query selection screen whose fields i want to create custom validations for. ( which should trigger when check or execute is pressed )
How can this be achieved ?
I tried looking for exits but did not find a relevant one.
Thanks in advance.

Hello,
You need to write a routine in SMOD for selection screen validations.
It will come in i_step = 3. please refer foll code as example:
The code example is to check whether date is less than or equal to current date. If user enters future date it pop ups saying enter date less than or equal to current date.
DATA:  LI_VAR like rrrangeexit,
       wa_t_var_range like LI_VAR,
       count type i value 0.
IF i_s_rkb1d-infocube EQ 'CUBE1' or
   i_s_rkb1d-infocube EQ 'CUBE2'.
Check whether only one of date variable is entered in variable screen.
IF I_STEP = 3.
    Read table i_t_var_range into wa_t_var_range with key vnam = 'VARDATE'.
      if wa_t_var_range-low > sy-datum.
        CALL FUNCTION 'RRMS_MESSAGE_HANDLING'
          EXPORTING
            I_CLASS  = 'RSBBS'
            I_TYPE   = 'E'
            I_NUMBER = '000'
            I_MSGV1  = 'Enter date less than or equal to current date'.
        raise again.
      endif.
ENDIF.
ENDIF.
