The rights in clarity either give you access to a functionality or data (view or edit) or both.
The global rights related to reporting are
Advanced Reporting - Ad Hoc Create |
Advanced Reporting - Administer |
Advanced Reporting - Dashboard Create |
Advanced Reporting - Data Source Create |
Advanced Reporting - Domain Create |
Advanced Reporting - Navigate |
Advanced Reporting - Report Create |
Reports - Access |
Reports - Run - All |
Reports - View Output - All |
Reports and Jobs - Administrator Access |
Reports and Jobs - Create Definition |
Reports and Jobs - Edit Definition - All |
The rights are not menu dependent so it does not matter where in the menu the subject of a right is.
In your case it is likely to be Advanced Reporting - Navigate and maybe also Reports - Access.
Note that if you have Advanced reporting elsewhere in the menu the same rights apply to that and your custom menu item.
Then you would limit the data that can be accessed with instance rights.
However, with reports and specifically Advanced reporting you are out of luck.
The report related instance rights are
Project - Create - Status Report |
Project - Edit All - Status Report |
Project - View All - Status Report |
Report - Run |
Report - View Output |
Reports and Jobs - Edit Definition |
Nothing related to advanced reporting.
