Oracle Internal Service Request uses the Management Chain Rule, in the Management Chain Ruleset, which includes a condition (IF) statement and an action (THEN) statement. The condition statement simply ensures that a service type has been selected. The action statement creates a list of managers whose approval is required based on the following information:

- The service request subtype, which determines how many levels of management approval are normally required for a service request.
- The identity of the submitting employee, which determines the specific managers whose approval is needed.

You can modify the existing ruleset, conditions, or actions. Take caution before modifying a condition or action, it can require source code changes. Service request processing fails if this ruleset is deleted. To modify the ruleset, conditions, or actions, see "Editing Rules in an Oracle Business Rules Dictionary at Run Time," in Oracle Fusion Middleware User's Guide for Oracle Business Rules.
