Adhoc Query Issue - How to restrict /SAPQUERY/H2 access

Hi Experts,

I have created two User Groups HR_1 (assigned to infosets for Time data) and HR_2 (assigned to Infosets for Payroll data). Also, I want to assign the HR_1 to a user Time_admin and HR_2 to Payroll_Admin, so that Payroll admin do not have access to Time data and vice versa.

Now I can restrict the access but when I execute the Adhoc query for the user, I can see the User group that I have assigned with a default user
group /SAPQUERY/H2, which has access to all data.

My question is, how can I restrict the access for the /SAPQUERY/H2 for the users so that the users have only access to their user groups i.e.,
Time_admin to HR_1 only and Payroll_admin to HR_2 only.

Regards

Vikrant
