Use the Assign Class Codes page, after you have created a class category and its class codes, to make one class code the parent of another class code in a class code hierarchy. This option structures class categories and class codes in parent-child hierarchal relationships.

The assignment of parent class codes is restricted by the options available for the class category. When you create or update a class category, you can check or clear the Allow Multiple Parent Codes check box, which allows or prevents a class code from having more than one parent class code.

You can update class code definitions, including parent codes, in the Update Class Code page. See: Updating a Class Code.

To assign a parent class code to a new class code:

1. Create new class codes for a new category. See: Creating a Class Code.

2. In the Class Codes region, select the child class code of the parent-child relationship that you are creating.

3. Click the Assign Parent Class Codes button to navigate to the Assign Class Codes page.

4. Select a parent class code, or one or more if allowed.

   • If the Allow Multiple Parent Codes option is selected, then you can select one or more class codes.

   • If the Allow Multiple Parent Codes option is not selected, then you can only select one class code.

5. Click the Assign button.
