Month-to-Date and Year-to-Date values in Query

Question

Hello experts,
One of our BI reports has the following requirement: the user should be asked for the report date. After the user inputs the date, the report shows the key figures in three different "flavors": one is the values for that date, the second one is the cumulate values from the first day of the month of the report date to the report date itself, and the third is the cumulate values from the first day of the year of the report date to the report date itself.
  I created my report date variable based on 0CALDAY. Then I searched for SAP-exit variables that would help me achieve this, but could not really find any, except for 0P_ABO10, 0P_ABO11, 0P_ABO12 variables, all of them have as description "Start of Key Date Year". I tried creating a few selections in which the dates taken were defined as a range from each of these variables to the report date variable (for the year-to-date values), but I got the error "Variable 0P_ABO10 could not be substituted". I also got this error for the other two variables. And I could not find any SAP-exit variables like "Start of Key Date Month", in order to do the Month-to-Date part. My next try was to use the field "Key Date" with a variable in it, instead my own report date variable based on 0CALDAY, but it gave me the same errors.
I searched the forums and found a few threads that looked useful, like
First and Last day of month and
1st day of month / 1st day of week variables
However, they require some ABAP coding, and I do not know where to place the code (actually, I do not know where to work with ABAP code), and I also believe that I would have to do some changes to it.
Any suggestions?

Hi Pedro,
You have to create customer exit in T_Code: CMOD
1. Create a Z project
2. Select RSR00001 as enhancement type.
3. Go into include ZXRSRU01
4. create a code like
Here A is your variable based on 0calmonth with type customer exit and B is variable for 0calday.
Try to write logic for your case taking this as example.
WHEN 'A'.
    IF I_Step = 2.
      Loop at I_T_VAR_RANGE into L_T_VAR_RANGE where VNAM = 'B'.
        Concatenate L_T_VAR_RANGE-LOW(4) '001' into D1.
        Concatenate L_T_VAR_RANGE-LOW(4) '012' into D2.
        Clear L_S_Range.
        L_S_Range-low = D1.
        L_S_RANGE-high = D2.
        L_S_RANGE-sign = 'I'.
        L_S_RANGE-opt = 'BT'.
        Append L_S_Range to E_T_Range.
      ENDLOOP.
    ENDIF.
If you want exact code I can help you in that.
Thanks,
