A user has Administrator permissions for a given function (e.g. Sales order, Dispatch, etc) if the permissions that are configured for that user (or the user’s group) has the Administer property set for either the function in question or the function’s group.
A user with Administrator permissions for a function may be allowed to perform special actions that other users cannot. The Help for each form details special actions allowed by Administrators for that function.
See Permissions for details about how to set a user up to become an Administrator of a function or a group of functions.
