Use case 4 is similar to use case 2, except that you want the information or promotion to show up on the external website in addition to the internal web application. This scenario should be created in the external cluster because the customer is main subject. Because you use the Add Promotion to Profile action, the promotion will be persisted to the customer’s profile. When the agent helps this customer using ATG Service Center, the promotion that was persisted to the customer’s profile will be displayed. There is no need to create or run the same scenario in the internal cluster.
This slot is passive because it is triggered by a customer’s purchase on the external website. You pick External Profile to make the slot customer-aware because the customer is the main subject of the scenario (his actions trigger the scenario).
