In the Expiration section, set Access package assignments expires to On date, Number of days, Number of hours, or Never.
For On date, select an expiration date in the future.
For Number of days, specify a number between 0 and 3660 days.
For Number of hours, specify a number of hours.
Based on your selection, a user's assignment to the access package expires on a certain date, a certain number of days after they are approved, or never.
