Guidelines for Defining the Tree Structure

You may create a tree structure from scratch or use any predefined tree structure. To complete the tree structure definition, specify the required details on the Create Tree Structure: Specify Definition page.

Tree Node Selection

The data in Tree Node table maps to the data in nodes of the tree structure. You must select the correct and most appropriate tree node table to define the tree structure, based on which you establish the tree hierarchy. This selection also affects the level of security that's set on a tree node and its child entities.

Tree Sharing Mode

Use the following options to determine the mode of sharing a tree structure across the applications.

• Open: Indicates that the tree is associated with all reference data sets.

• Set ID: Indicates that the tree is associated with a specific reference data set.

Modification

You can modify the predefined tree structures as well as those you create. However, modifying a predefined tree structure is restricted and permitted through additional privileges. Modification is limited to specific tree nodes and lower in the tree hierarchy.

Multiple Tree Versions

Although multiple tree versions can exist together, Oracle recommends that only one version be active at any given time. However, if required, you can have more tree versions to be in the active state for the same date range. You can use this flexibility to select the tree version you want to implement.
