How to use cusomer exit to set month-revelant auth setting for reporting

Hi,

Our Client has a req regarding reporting authorization in BI2004s. They don't allow their employees' to view sales revenue and gross profit of LAST MONTH. But this restriction only effective in the beginning three days of each month.

We realize that we can activate setting "Auth revlevant" for Calendar Year month and restrict certain month for viewing data purpose. But if we want the auth req "data of last month not allowed in the beginning thress days of each month", can we do it with Customer exit for "Calendar year /Month"? If YES, can anyone please tell us how, or any better idea to solve this issue??

Thank you very much.
