To define security rules:

1. Navigate to Define Security Rules window.

2. In the Segment Values block, identify the value set to which your values belong. You can identify your value set or by the flexfield segment or concurrent program parameter that uses the value set.

3. In the Security Rule region, enter a name and description for your security rule.

4. Enter a message for this security rule. This message appears automatically whenever a user enters a segment value that violates your security rule.

5. Define the security rule elements that make up your rule. See: Defining Security Rule Elements.

6. Save your changes.
