Can i assign a string to a variable in User Exit?

Question

Friends,
I would like ot write a User Exit that will assign a string to a variable depending on the value of the other variable.
I just wanted to know if such a code is valid:
When zimport
IF i_step = 2.      " read user input parameter
        l_s_range-low = 'Important'.
     APPEND l_s_range TO e_t_range.
    ENDIF.
If so, my second problem is that in the variable exit definition with processing Customer type you need to identify a "Dimension" for the variable. Non of them really fit, because the value is a string so why convert it to another format?
Your input is appreciated in advance,
Xibi

Answer 1

hi Xibi,
say you have var1 and var2, var2 will be filled depend on value of var1, you can write something like following.
please be remind that var2 is not marked as “ready for input” and is set to “mandatory variable entry”.
hope this helps.
The second step (I_STEP = 2) is called after the processing of the variable pop-up. This step is called only for those variables that are not marked as “ready for input” and are set to “mandatory variable entry”.
WHEN 'var2'.
    IF I_STEP = 2.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
              WHERE VNAM = 'var1'.
        CLEAR L_S_RANGE.
        if LOC_VAR_RANGE-low = ...
          L_S_RANGE-LOW = 'IMPORTANT'.
        else.
          L_S_RANGE-LOW = '....'.       
        endif.
        L_S_RANGE-SIGN   = 'I'.
        L_S_RANGE-OPT    = 'EQ'.
        APPEND L_S_RANGE TO E_T_RANGE.
      ENDLOOP.
    ENDIF.
