I have a rule on Staff object which is a member of the SystemUser group
If LoggedInStaff.AccessLevel<>'Administrator' AND Staff.AccessLevel='Administrator' Then
PROTECT Staff FROM ALL EXCEPT Administrator AND System
But while greying out all the fields, this rule does not protect an administrator from being deleted by a non administrator. Is it how the system should work or is it a bug? I am still using an old build 907. Thank you.
