There are two instances of Banner at Auburn: Banner Admin and Banner Self-Service. Both are available through the Web to those with appropriate access.
Most campus users will use Banner Self-Service. Only administrative systems "super users" (like office administrators) will have any need to use Banner Admin.
What is the difference?
Banner Self-Service is web-friendly and is used to complete most general processes like viewing & querying budget, and approving documents such as requisitions and budget transfers. As additional components of Banner are implemented on campus, Banner Self-Service may be used for processes like submitting leave and time sheets, viewing paycheck or direct deposit stubs, and student functions.
Banner Admin is used by administrative "super users" (like Office Managers and Business Office employees, for example). Banner Admin offers some additional features necessary to complete specific administrative functions in support of AU business processes. Most campus users will be able to do everything they need through Banner Self-Service.
