Creating User Exit Variable in BeX

Question

Hi All,
Urgent help required.
I need to create User Exit for a variable which reads value from other variable value which user enter during pop up.
Ex: I need get value for the vaiable "ZACTFY" from the variable value "ZSCENARI". Value of this ZSCENARI will be like
200684
200693
200757 ....
where 2006, 2007 specify year of the forecast value and from (200684) the value 8 refers to 8 months actual & 4  refers to 4 months plan values.
So if ZSCENARI is 200684 the value for the variable ZACTFY should be in interval. i.e Range for low value should be 001.2006 (always month is Jan and year taken from first 4 digits of ZSCENARI) and hight value should be 008.2006.
No need to worry about plan values for scenario 200684 plan value will be there only for last 4 months.
1. Can any one tell me how to do coding for this(pls let me know including declaration).
2. Also if the value for ZSCENARI is Multiple single values lets say the user enters as 200684,200693,200657.. Pls tell me how we can do coding for this.
Thank You.
Best Regards,
Bhuvana.

Hi,
CASE I_VNAM.
  WHEN 'ZACTFY'.
   IF I_STEP = 2.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
        WHERE VNAM = 'ZSCENARI'.
        CLEAR L_S_RANGE.
        L_S_RANGE-LOW = LOC_VAR_RANGE-LOW(4).
        L_S_RANGE-LOW+4(2) = '01'.
        L_S_RANGE-high = LOC_VAR_RANGE-LOW(4).
        L_S_RANGE-high4(2) = LOC_VAR_RANGE-LOW4(1).
        L_S_RANGE-SIGN = 'I'.
        L_S_RANGE-OPT  = 'BT'.
        APPEND L_S_RANGE TO E_T_RANGE.
      ENDLOOP.
    ENDIF.
