Notes
• The Convert Subtype Relationships to Recursive Relationships check box allows you to preserve relationships
between subtypes when rolling up subtypes into a supertype. The relationships will become recursive. The
rolenames in the subtypes will be used in the supertype. Otherwise this page is merely informative. If the correct

• If the Rollups menu choice is grayed, check to make sure you have not accidentally selected another table or
some other object.
