FIAR report..

Question

Hi all ,
We r working on FIAR overdue report .
I have to display the Amount key figure from the 0FIAR_O03 ODS based on the following conditions:
1.Key date(in selection screen) > Net due date
2.Posting date <= key date(in selection screen)
3.Clearing date > Key date(in selecvtion screen)
I have created the restricted key figures and used variable offsets like below
to calculate Overdue Amounts < 180 and > 180 days.
ex. for < 180 days overdue amount
For less than 180 days:  Restricted keyfigure with netduedate >= keyduedate-180;keyduedate-1
For greater than 180 days : Restrcited keyfigure with net duedate < keyduedate - 180 .
Now user wants instead of having 180 days, he wants to enter Days in selection screen alongwith key date.
For ex.user may want to enter 30 days or 60 days or 90 days.
User dont want to create more columns for 30,60,90 insteand of that he wants to enter in selection screen.So that report has to be generated based on the user input.

Answer 1

So for this i creates a bex exit variable in CMOD -RSR00001-EXIT_SAPLRRS0_001.
Let me explain in more detail .
ZVAR4 is my bex variable ( single value ) .
0P_KEYDT is my Keydate.
ZDAY is my User enterd variable .
for greater than 180 : Restricted keyfigure netduedate < ZVAR4 .
for less than 180 : Restricted keyfigure netduedate in between [ZVAR4 AND KEYDATE]
Iam using the following code
CASE I_VNAM.
  WHEN 'ZVAR4'.
    IF I_STEP = 2.
      CLEAR L_S_RANGE.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
      WHERE VNAM = '0P_KEYDT'.
        key_date = LOC_VAR_RANGE-LOW.
        EXIT.
      ENDLOOP.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
      WHERE VNAM = 'ZDAY'.
        offset = LOC_VAR_RANGE-LOW.
        offset = offset - 1.
        EXIT.
      ENDLOOP.
      key_date = key_date - offset.
      L_S_RANGE-LOW = key_date.
      L_S_RANGE-SIGN = 'I'.
      L_S_RANGE-OPT = 'EQ'.
      APPEND L_S_RANGE TO E_T_RANGE.
    ENDIF.
endcase.
