Hi,
2. when i excute the program, it shows value 5.33 for current month. (0CALMONTH is restricted with variable (ZVAR_12M-11 - ZVAR_12M).
When i change the variable with previous year with variable restriction (ZVAR_12M-12 - ZVAR_12M-1), it shows current month value (5.33).
dont restrict the customer exit variable in restricted keyfigure with offset values. your code is already handling it.. no need to use any offset. just restrict keyfigure with 'zvar_12mm' .
run the query in rsrt, you should see the month ranges in the same RSRT screen (just scroll below).. if the ranges are incorrect..then you can investigate.
alternative try the code which i gave and see.
