Set up SAP S/4HANA Cloud Public edition connectivity with SAP Cloud Application Event Hub

Depending on how your SAP BTP global account is setup, an SAP S/4HANA Cloud Public edition system may already be registered in your SAP BTP global account. Follow the steps below in case your SAP S/4HANA Cloud Public edition system is not registed.

1. Go to the SAP BTP cockpit and navigate to the System Landscape section. Here you will find all systems registered in your system landscape. Given that we’ve already created an instance of SAP Cloud Application Event Hub, you will see it listed here.

2. Choose the Add System button. Set the System Name and select SAP S/4HANA Cloud as the System Type.

   

3. In the dialog, select the Communication Scenario Groups Eventing Between SAP Cloud Systems and copy the value in the Registration Token. This token will be used in the next step when we add our SAP BTP account in SAP S/4HANA Cloud.

   

1. In SAP S/4HANA Cloud, go to the Maintain Extensions on SAP BTP application.

2. Choose the New button. Enter the token copied from the previous step in the Integration Token field and set a meaningful description that can identify the SAP BTP global account. Once completed, choose the Create button.

   

3. Approve the extension creation by clicking the Yes button.

   

Once we’ve approved the extension the extension status will change to enabling and after a few seconds it will be enabled. Also, in the SAP BTP system landscape, you’ll noticed that the SAP S/4HANA Cloud will now have a status of Registered.

Now that we have the SAP S/4HANA Cloud Public edition system registered in our SAP BTP global account, we can proceed to include it in a formation. The formation will need to be of type Eventing between SAP cloud systems to enable the event exchange.

1. In the SAP BTP cockpit, navigate to the Formations section, choose the Include Systems button in the formation.

   

2. In the pop-up, select the SAP S/4HANA Cloud Public edition system you just registered. Then, choose the Next Steps button.

   

Once the formation finishes synchronizing, the SAP S/4HANA Cloud Public edition system will be part of the formation. SAP Cloud Application Event Hub will take of the necessary communication between SAP S/4HANA Cloud and itself. It will generate a communication system and communication arrangement in SAP S/4HANA Cloud.

We can optionally check the components created in SAP S/4HANA Cloud. For this, we will leverage the functionality available in the Enterprise Event Enablement - Channel Binding app.

1. In SAP S/4HANA Cloud, go to the Communication Arrangements app and filter by the .

   

2. Alternative, we can go to the Enterprise Event Enablement - Channel Binding app and a new channel will be listed representing the connection to SAP Cloud Application Event Hub. The channel will have a name similar to the name set for the formation in the SAP BTP cockpit.
