For each parent-child hierarchy defined on a relational table, you must explicitly define the intermember relationships in a separate parent-child relationship table. In the process of creating the parent-child relationship table, you may choose one of the following options: 1. Select a previously-created parent-child relationship table. 2. Use a wizard that will generate scripts to create and populate the parent-child relationship table. In the next set of steps you select a
previously created and populated parent-child relationship table. For your information only: To start the wizard you would click the Create Parent-Child
Relationship Table button. The wizard creates the appropriate repository metadata objects and generates SQL scripts for creating and populating the parent-child relationship table. At the end of the wizard, Oracle BI Server stores the scripts into directories chosen during the wizard session. The scripts can then be run against the database to create and populate the parent-child relationship table. Running the wizard is not necessary in this tutorial because the parent-child relationship table is already created and populated.
2 . Click the Select Parent-Child Relationship Table button to open the Select Physical Table dialog box.

2

3 . In the Select Physical Table dialog box, select the D51 Sales Rep Parent Child alias you created.

2

4 . The D51 Sales Rep Parent Child alias is now displayed in the Parent-Child Relationship Table column.

5 . In the Parent-Child Table Relationship Column Details section, set the appropriate columns:

Member Key MEMBER_KEY
Parent Key ANCESTOR_KEY
Relationship Distance DISTANCE
Leaf Node Identifier IS_LEAF

2

Explanation:
Member Key identifies the member.
Parent Key identifies an ancestor of the member, The ancestor may be the parent of the member,
or a higher-level ancestor.
Relationship Distance specifies the number of parent-child hierarchical levels from the member
to the ancestor.
Leaf Node Identifier indicates if the member is a leaf member (1=Yes, 0=No).
6 . Click OK to close the Parent-Child Relationship Table Settings dialog box.
