Hi guys, in this article I want to share a scenario end to end How to connect business processes with external system like SAP S/4 HANA on-premise, S/4 HANA public cloud by using action feature in SAP Process Automation.

You can use mode on-premise OR public cloud, it’s the same configuration.

In this article, I do not have account product for S/4 HANA public cloud so I will do this by using model ON-PREMISE.
