Consuming messages from SAP Enterprise Messaging queue

[dmitry_garkush]

Hi,

Is the only way to consume messages appeared in EM queues to call an endpoint?

For example, if we consider setup 3rd party -> SAP EM -> SAP S/4HANA, there must be a custom program in S/4 constantly polling EM for new messages?

Thank you.

Hi Dimi,

as of today S/4HANA is only acting as an event publisher. At the moment S/4HANA is not supporting any subscription mechanism to SAP Enterprise Messaging to consume events.

I'm not an S/4HANA expert so, but these are the options supported by SAP Enterprise Messaging:

• Consumption via Messaging protocols MQTT or AMQP
• Consumption via REST interface (pull-based approach)
• Consumption via WebHooks (push to REST endpoint)

Regards,
Tobias

Hi Tobias,

Curious, if it'd be possible to utilize MQTT or WebHooks for EM events consumption in S/4HANA.

The former is supported according to S/4HANA documentation and the latter should (?) work with standard S/4HANA OData endpoints.

Need to try that.

Kr, Dimi
