Set up SAP Cloud Application Event Hub

1. Log in to your SAP BTP account and navigate to Services > Instances and Subscription. Choose the Create button.

   

2. In the popup, select the service SAP Cloud Application Event Hub and select the plan standard.

   

3. Once the instance is created, it will be listed in our subscriptions.

   

1. Navigate to the Security > Users and select the user you want to assign the role to.
2. Go to Users and select the user you want to assign roles to. Choose the … button and then choose Assign Role Collection.
   
   
3. In the Assign Role Collection popup, assign the following role:
   • Event Broker Integration Administrator
     
     
4. Choose Assign Role Collection button.

Now the user has the required role to access the SAP Cloud Application Event Hub UI.

In order to enable eventing between SAP cloud systems, we need to create an Eventing Between SAP Cloud Systems formation. At the moment we will not enable the exchange of events but just create the formation with an instance of SAP Cloud Application Event Hub so that it is ready and then we can start adding systems later.

1. Navigate to the Global account, and select Formations under the System Landscape section. Then, click on the Create Formation** button.
   
   
2. Enter a name and select the formation type Eventing Between SAP Cloud Systems. Then, click on the Next Steps button.
   
   
3. Now, select the instance of SAP Cloud Application Event Hub you created earlier. Then, click on the Next Steps button.
   
   
4. Finally, review the information and click on the Create button.

A new formation will now be listed in the Formations section.

Now we’ll access the SAP Cloud Application Event Hub UI and get familiar with the different sections available.

1. Navigate to the Services > Instances and Subscription.
2. Select the instance of SAP Cloud Application Event Hub you created earlier.
3. Click on the Go to Application button.

The first time you access the SAP Cloud Application Event Hub UI, you will have no subscriptions. In the screenshots below, we will show you what a fully configured SAP Cloud Application Event Hub instance looks like.

1. My Subscriptions: All active subscriptions will be listed here.
2. All available subscriptions: Here you can see all the subscriptions available in the instance. In essence, any integration dependency that has been defined for all systems in the system landscape will be listed here.
3. For each subscription, we will see the name of the subscription, the system publishing the events, the system subscribed to the events and the status of the subscription. When a subscription is active, events will be flowing from the publishing system to the subscribing system.

In the Event Hub - basic concepts tutorial, we can get familiar with the basic concepts required to start using SAP Cloud Application Event Hub.

In this tutorial, we created an instance of SAP Cloud Application Event Hub and got familiar with its UI.

Things to Ponder

1. If I need to disable a subscription temporarily, where would I do that in the UI?
2. Can I apply filters to the events being sent to a subscribing system?
3. Which SAP cloud applications are supported as event publishers?
