You can configure your deployment so that anyone assigned to the system administrator role can see new sets created by anyone in that role automatically. This way, all system administrators can view or edit sets created by other system administrators.
If system administrators have already created sets before you enable this setting, the setting affects only the sets that your administrators create after the setting is enabled. If you want your system administrators to access any sets that were created before you enabled the setting, you need to explicitly grant permission to those sets.
By default, this setting is not enabled.
To specify that all system administrators can access sets created by anyone in the system administrators role
Go to Settings > Resources > General > Security settings, and enable the following setting:
Automatically grant all set permissions to the system administrator role when a system administrator creates a new set.
