To prevent users from inadvertently making modifications, in the namespace, you want to restrict write access for all entries in a hierarchy to only Report Administrators.
In ATG Reporting Center, locate the top-level folder in the hierarchy.
In the Actions column, click the Set properties button for the folder.
In the Set properties page, click the Permissions tab.
Select the Override the access permissions acquired from the parent entry check box.
Click Add, then click the namespace, and then select the check boxes next to all the users, groups, or roles.
Click the right-arrow button, then click OK.
To grant Report Administrators write permission, select the Report Administrator check box, select the grant write access check box, and click Apply.
To deny all other listed users, groups, or roles write permission, select the check boxes, click the deny write access check box, and click Apply.
Select the Delete the access permissions of all child entries check box.
Click OK. Now, only Report Administrators have write access to the content of the top-level folder and all its subfolders.
