i have create a exit type variable and assign to a query as filter.
and in CMOD add code to program: EXIT_SAPLRRS0_001
But the exit doesn't work , i set break-point but it doesn't stop at all.
READ TABLE I_T_VAR_RANGE INTO L_S_VAR_RANGE WITH KEY VNAM = 'ZFISYEAREXIT1'.
IF SY-SUBRC = 0.
L_S_RANGE-LOW = sy-datum(4). "low value, for example, 2007
L_S_RANGE-HIGH = sy-datum(4). "high value = input
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT = 'BT'.
APPEND L_S_RANGE TO E_T_RANGE.
