Property Grouping

Indicates whether the level contains member groups. Member groups can be used to satisfy the maximum limit of 64,000 members under a parent. To use member groups in this way, create a new level immediately above and identical to the level that exceeds the limit, and then set the new level's Grouping property to Automatic. For more information, see Member Groups.
