Query - customer exit help

Question

I asked this question previously, but did not clear answers. Just for clarification - in my DSO there is just one date field (0calday), one characteristic (ZTYPE) and one key figure (ZRATE)
User will enter one date : September 03, 2008 , the query must display all values till the beginning of the month
September 03, 2008 --- Type 1 - 1.5
September 02, 2008 --- Type 1 - 2.0
September 01, 2008 --- Type 1 - 3.0
September 03, 2008 --- Type 2 - 6.0
September 02, 2008 --- Type 2 - 3.6
September 01, 2008 --- Type 2 - 2.8
Solution : This is how I'm planning to do it:
Create one variable based on 0calday for user input (Zuserdate). Create another variable (Zdatrange) on 0calday for processing by customer exit. The "to date" is same as the user-entered date and the "from date" DD is hardcoded to "01" and MM/YYYY is derived from user entered date? Is this the approach? I'm not very well aware of ABAP coding so would appreciate your help.
Thanks.

Answer 1

Dear Anita,
Your approach right. Try the following code in the customer exit.
CASE I_STEP.
   WHEN '2'.
     CASE  I_VNAM.  " Name of your customer exit variable
        WHEN 'ZDATRANGE'
        READ TABLE I_T_VAR_RANGE INTO LOC_VAR_RANGE WITH KEY
                                                                VNAM = 'ZUSERDATE'
                                                              IOBJNM = u20180CALDAYu2019.  " Get user input date
        IF SY-SUBRC = 0.
          L_S_RANGE-HIGH = LOC_VAR_RANGE-LOW.      " high value = input
          L_S_RANGE-LOW = LOC_VAR_RANGE-LOW(6).  " low value, e.g.200701
          L_S_RANGE-LOW+6(2) = '01'.                               " for 1st day
          L_S_RANGE-SIGN = 'I'.
          L_S_RANGE-OPT = 'BT'.
          APPEND L_S_RANGE TO E_T_RANGE.
        ENDIF.
     ENDCASE.
ENDCASE.
