Extending SAP S/4HANA Cloud

SAP Business Technology Platform

SAP BTP provides a standard way for extending SAP solutions. In this article we cover SAP S/4HANA Cloud.

The tutorial series assumes you have a Kyma environment running. For this, see

For additional information about extending cloud solutions in general and SAP S/4HANA Cloud and the Kyma environment in particular, see Learn More below.

Register an SAP S/4HANA Cloud System (api-access)

Video Tutorial

In this video, we show how to register an SAP S/4HANA Cloud system, including entitlements and creating a service instance using the Kyma Dashboard using different communication scenarios.

The components involved are illustrated below. Note that for the Kyma environment, the Extensibility Service uses the Kyma runtime with the Destination Service created at the subaccount level. A Cloud Foundry environment is not required.

Service instances for the SAP S/4HANA Cloud Extensibility service are created using the Kyma Dashboard under Service Management, Catalog. This is limited to a single service instance per namespace.

From the instance view, we can bind an application to a service instance and create credentials, a Kubernetes “secret” object, the functional equivalent of a Cloud Foundry “service key”.

SAP S/4HANA Cloud Communication Management

Communication is based on a communication scenario (design time), which describes the meta data needed to set up the communication arrangement (runtime) in your system.

  • A communication scenario is a design time description of how two communication partners communicate with each other. It provides technical information, such as the used inbound and outbound services and their service type, for example OData or SOAP, and the number of allowed communication arrangement instances.
  • A communication arrangement is a runtime description of a specific communication scenario. It describes which communication partners communicate with each other in the scenario and how they communicate.
  • A communication system is a specification of a system that represents a communication partner and the technical information required for the communication (inbound/outbound), such as the host name/IP address, user information (inbound/outbound), certificates, etc.

APIs usually come with a predefined communication scenario. To use the APIs, you first need to create a communication arrangement based on the communication scenario.

On the SAP API Business Hub, check the Details tab of an API to see which communication scenarios it is part of. You can also search for a communication scenario to see which APIs it contains.

The Display Communication Scenarios app lists all SAP and partner/customer-managed scenarios.

The Communication Arrangement app lists the arrangements created when we add an SAP S/4HANA Cloud Extensibility service instance with plan api-access using the Kyma Dashboard.

Selecting the entry displays the Communication System configuration (editable).

Register an SAP S/4HANA Cloud System (messaging)

Video Tutorial (Coming Up)

In this video, we show how to create a service instance for SAP S/4HANA Cloud Extensibility (messaging) and for SAP Event Mesh (default) using the Kyma Dashboard and for the SAP Event Mesh web application (standard) using SAP BTP Cockpit. Create outbound topics using the Enterprise Event Enablement app of SAP S/4HANA Cloud and create queues and subscriptions using the SAP Event Mesh app.

Procedure

Create service instances for the SAP S/4HANA Cloud Extensibility Service messaging plan and the SAP Event Mesh default plan using the Kyma Dashboard.

Use the SAP S/4HANA CLoud Communication Scenario app for information about scenario Enterprise Eventing Integration scenario (SAP_COM_0092).

For configuration sample of the JSON service descriptor file, see

SAP S/4HANA Cloud Extensibility service descriptor

Event Messaging service descriptor

Use the SAP S/4HANA Cloud, Enterprise Event Enablement app, Maintain Event Channel Binding to add outbound topics.

Create a queue for the message client and add subscription(s).

Over the years, for the SAP HANA Academy, SAP’s Partner Innovation Lab, and à titre personnel, I have written a little over 300 posts here for the SAP Community. Some articles only reached a few readers. Others attracted quite a few more.For your reading pleasure and convenience, here is a curated list of posts which somehow managed to pass the 10k-view mile stone and, as sign of current interest, still tickle the counters each month.
