drill-down capabilities and security implementation across different levels of h

Hi,

How to create the in crystal reports having drill-down capabilities and security implementation across different levels of hierarchy?
For instance, they can create a report having billing and booking Qty. that can be drilled-down across time dimension. Different levels could be year, month, week etc. Security should be implemented in such a way that a particular group of users can see data only at the week level, second group of users can see data at the month as well as the week level and third group can see all three - year, month and week data.

Can anybody helpppp??

CR is just a reporting tool, if u implement the security feature in the database that is accessed by the report, then you don't need to bother about it in the reports.
