Editing the Validation Groups Hierarchy 

Procedure

Validation groups are organized into a hierarchy. The Validation Groups hierarchy is similar to the Data Groups hierarchy in that it does not show up in the drop-down list of tables and cannot be edited directly.

Instead, you can modify the Validation Groups hierarchy by choosing Records ® Validations ® Edit Validation Groups from the main menu to open the Edit Validation Groups Hierarchy dialog, and then using the context menu as in any editable tree to add siblings and children, and to delete and rename existing nodes (figure below).
