When getting rights...
These options are used when VSys Security is in advanced mode and VSys is looking to determine if, for a particular person, the current user is a supervisor of that person. They determine how far into the past and future VSys will look for assignments in which the current user is the supervisor for an assignment with this person as the volunteer. Setting both of these to 0 prevents assignment-based supervisors from being considered here.
When processing VSys Live applications...
If checked, when using the VSys Live applications approval tool, if the current user has rights to an application by virtue of the application type, requested department or requested site, VSys will consider the user to have rights to the person as well.
