Building a Real‑Time Currency Conversion iFlow using SAP Cloud Integration (CPI)
A step-by-step build of a currency-conversion integration flowIntegration flowsMoving and transforming messages between systems in middleware instead of in application code: an integration flow with its adapters and mappings, and the runtime it executes on. Reaching a remote system from application code is destinations, and brokering events between systems is Event Mesh.SAP only in Cloud IntegrationCloud IntegrationBuilds and runs integration flows that process, route and map messages between cloud and on-premise systems, SAP and non-SAP, through prebuilt adapters; available only under an SAP Integration Suite plan.sap official, btp: an HTTPS sender adapter accepts JSON, a content modifier stores the currencies and amount as exchange properties, and a Request-Reply step calls an external rate API before a Groovy script renders the result as an HTML table. A Global Exception Subprocess centralizes error handlingError handlingTurning a failure into a response a client can act on — protocol-correct error payloads, correlation, and a boundary between internal detail and what a caller sees.SAP and community, unassessed for the whole flow, turning the MPL ID, error type and message into HTML and mailing it as a notificationNotificationsTelling a person something happened when they are not looking at the screen — a notification in the launchpad, an email, a message somewhere they already are.SAP and community, narrow by design to a support address.
