Hi Team,

Can some one help me to understand, how to restrict the data in reports.

For example we have one of the report called Leave Balance Report. It contains all employees absence details.

As a super admin I call access all employees absence records. But when my HR try to access the all the employees absence record she can't able to access.

So, how can they restrict. If I want to provide my HR also access all the absence records how can I do that.

Please can some one help me on this.
