The system watches for the order approval system to indicate that an order has been approved or rejected by an approver. You can use the optional parameters within this element to further define the type of order to watch for.

Technical Note: This element is triggered when the ScenarioManager receives an ApprovalUpdate message. The ApprovalUpdate message is sent by either the sendApprovalUpdateMessageForApproval processor (class atg.commerce.approval.processor.ProcSendApprovalMessage) in the orderApproved pipeline chain or the sendApprovalUpdateMessageForRejection processor (class atg.commerce.approval.processor.ProcSendApprovalMessage) in the orderRejected pipeline chain, depending on whether the approver approved or rejected the order. For more information, see the Managing the Order Approval Process chapter in the ATG Commerce Programming Guide.
