Case groups are used to record details of the assistance, financial, and member groups. When a product delivery is created during authorization/activation, each group type is automatically created. Subsequent execution of the eligibility rules for the specific program may result in a new assistance, financial, or member group being created when the existing group composition changes. When a group member is no longer included in the group, they are displayed with an end date. Previous members who are no longer part of the group are also displayed.
