By default, the Navigator displays both table definitions and hierarchy definitions under a single node in the Sources folder. The Designer provides the following ways to organize these definitions in the Navigator:
Create separate repository nodes for the hierarchies.
Create business components for related sources.
To display hierarchies separately in the Navigator, set the Designer options to group sources by database name. Then, edit the hierarchy definition and rename the database name to Hierarchy.
To edit the database name for hierarchies:
In the Source Analyzer, double-click the title bar of the hierarchy definition.
The Edit Tables dialog box appears.
Click Rename.
The Rename Source Table dialog box appears.
Change the Database Name to Hierarchy.
Click OK twice.
You also need to change the Designer options to display definitions in the Navigator by database name.
