Hi,
Could you please confirm SEPM version?
SEP 11.x and SEP 12.1 have wide differences.
SEP 11.x administrator have limitation while providing access to other administrator
In SEP 12.1 by default, administrators have access to all features in a single domain. That is, the administrator can view and run reports, manage groups, remotely run commands, manage installation packages, and manage policies for that domain. The administrator can also run reports on all groups in the domain, except for any groups that migrated from Symantec Antivirus 10.x. You must explicitly configure reporting rights to these migrated groups.
Also, you can grant site rights to administrators to authorize them to fully manage a site, which includes managing the database and servers. When you create a new administrator, the administrator is not authorized to manage sites. You must explicitly grant site privileges to allow the administrator to fully manage sites in a single domain.
