Answer 1

Hi,
Let s say
var1 is from varaible
var2 is to variable
var3 is user exit variable
USe the code like this:
DATA:
l_s_range TYPE rsr_s_rangesid,
l_s_var TYPE rrs0_s_var_range.
DATA: LOC_VAR_RANGE LIKE RRRANGEEXIT.
DATA: LOC_VAR_RANGE2 LIKE RRRANGEEXIT.
WHEN 'VAR3'.
    IF I_STEP = 2.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
        WHERE VNAM = 'VAR1'.
      LOOP AT I_T_VAR_RANGE2 INTO LOC_VAR_RANGE
        WHERE VNAM = 'VAR2'.
        CLEAR L_S_RANGE.
        L_S_RANGE-LOW = LOC_VAR_RANGE-LOW(8).
        L_S_RANGE-HIGH = LOC_VAR_RANGE2-LOW(8).
IF LOC_VAR_RANGE2(8) = '00000000'.
        L_S_RANGE-HIGH = LOC_VAR_RANGE-LOW(8).
ENDIF.
IF LOC_VAR_RANGE(8) = '00000000'.
        L_S_RANGE-LOW = LOC_VAR_RANGE2-LOW(8).
ENDIF.
        L_S_RANGE-SIGN = 'I'.
        L_S_RANGE-OPT  = 'BT'.
        APPEND L_S_RANGE TO E_T_RANGE.
      EXIT.
      ENDLOOP.
      EXIT.
      ENDLOOP.
    ENDIF.
