The image shows an event flow diagram of a portion of an end-to-end basic integration. There are four components, labeled AdapterType, Native Role, Binding Role, and Application Role. They are connected by single-headed arrows. The RequestPurchaseOrder-Inbound process starts with the AdapterType (Interactions) component, then proceeds to the Passthrough RequestPurchaseOrder of the Native Role (ExpenseApp_Notifying-NR) component, then the Translate RequestPurchaseOrder of the Binding Role (ExpenseApp_Notifying-TR) component, and finally the Passthrough RequestPurchaseOrder of the Application Role (ExpenseApp_Notifying-AR) component. End of description.
