Before the BioStar 2.7.10, there were some limitation for the T&A custom admin user. For example, T&A custom admin user could not see the T&A rules and schedules which the admin user created. So T&A custom admin user could not check all T&A rules and schedules and could not understand the current operation correctly. Additionally, the T&A custom operator could not see and edit the rules and schedules which the higher authorized users, such as administrator and T&A operator, created.
From BioStar 2.7.10, the T&A custom admin user can check 'Time Code', 'Shift', 'Schedule Template', 'Rule' and 'Schedule' no matter which authority the user has. Also, depends on the user's authority, the user can edit or read the items.
