Configure SAP S/4HANA Enterprise Event Enablement to publish production-order business events to SAP BTP Event Mesh and consume them in a subscriber application

Steps

1. In the SAP Fiori launchpad, open the 'Enterprise Event Enablement' app; create a new channel and point it to your SAP BTP Event Mesh service instance by providing the service key credentials (messaging URL, client ID, client secret, token URL).
2. Add topic bindings in the channel configuration; for production order events use topic patterns such as sap/s4/1.0/MM/ProdOrder/Changed/v1 — the exact topic names are defined in the Business Event Catalog.
3. Activate the channel; S/4HANA will now publish CloudEvents 1.0-formatted JSON payloads to Event Mesh whenever the bound business object changes.
4. In BTP Event Mesh, create a queue and subscribe it to the topic using a topic subscription; configure the queue's access credentials for your consumer application.
5. In the consumer application, use the Event Mesh REST API (or AMQP) to poll or push-subscribe the queue; parse the CloudEvents envelope to extract the business object key (e.g., ManufacturingOrder number) and call back to S/4HANA OData APIs for full payload.
6. Handle duplicate delivery by storing and checking the CloudEvents 'id' field — Event Mesh guarantees at-least-once delivery, not exactly-once.
