Publish SAP DM data to MQTT Broker using trigger(Manage Subscription app)

[ankit12]

Hi Experts,

Use Case: MQTT is sending data to SAP DM and after processing the data SAP DM need to send (publish) the response(Acknowledgement) back to MQTT. 

Issue: as we understood is that if we select message publishing option in trigger(Manage Subscription) Action tab, then DM won't allow you to call the PPD and send the output. so as per understanding we can only send constant value to MQTT.

We have found out the way for publishing the message to MQTT broker. Pasting it in the answer for other members of community:

Publish MQTT Message is visible under ‘Built-in Services’ of ‘Automation Sequence’ as shown below. Choose Runtime Type as ‘Production Connector’ and Runtime Environment as Prod Connector webserver.  You can define the PPD and publish the MQTT message and same PPD can be called from PPD’s with runtime environment as Cloud/Edge.

* Make sure SAP Production Connector version is upgraded.
