Restrict Time characteristic filter at selection screen

Question

Hi,
I am trying to find out a solution for the below typical requirment which i have in my project.
The scenario is as follow:
I have a BEx report with many characteristics in the selection screen. There are three time characteristics in the selection screen based on which the report can be executed. The three time chars are CALDAY, CALMONTH and CALWEEK. Now the requirement is that we need to provide a functionality to the user to select only one of the three time char i.e. they can either input date filter or month filter or week filter.
If user tries to input filter on more than one time char then he shouldnt be able to execute the report and it should show some kind of message. Also if the user dosent select any one of them it should not run
the report.
Please provide any work around for the same.
Thanks,
Varun

Hi Varun,
Yes this can be acheived by coing the same in the CMOD.  Please follow the steps as given below -
Please excuse me if I have done any typo errors -
Goto to CMOD and write a customer exit for i_step = 3 as given below -
IF i_step = 3.
data: count type n.
count = 0.
LOOP at i_t_var_range INTO l_s_var where vnam = 'date_var'
                          OR vnam = 'month_var'
                          OR vnam = 'week_var'.
   count = count + 1.
ENDLOOP.
IF count > 2.                 "this is for multiple time range selection
CALL FUNCTION 'RRMS_MESSAGE_HANDLING'
EXPORTING
  I_CLASS = 'RSBBS'
  I_TYPE = 'E'
  I_NUMBER = '000'
  I_MSGV1 = 'Please enter either of Date/Month/Week'.
raise again.
ELSEIF count = 0.            "this is for no time range selection
CALL FUNCTION 'RRMS_MESSAGE_HANDLING'
EXPORTING
  I_CLASS = 'RSBBS'
  I_TYPE = 'E'
  I_NUMBER = '000'
  I_MSGV1 = 'Please enter at least Date/Month/Week'.
raise again.
ENDIF.
ENDIF.
Hope this helps.
