Allows a user to specify the users who will have permissions for the Work Package, as defined by the permissions specified in the Work Package’s Permission field. Typically, these users will have only read permissions for the Work Package. For example, if a Work Package is assigned the predefined “Default Permissions” permission, users entered into the Work Package User Reader field will have the permissions specified by the “Work Package Permissions” permission for User Reader (i.e., only Read permissions).
