For this workshop, there are prepared test users for you. Each user has its own space in a shared BTP Subaccount. Each user is assigned the Subaccount Viewer role, to be able to view the instances and subscriptions. Also each user is entitled to use the Business Application Studio (BAS). We recommend using BAS as development environment, as all the tools are automatically installed and up to date there. Please note however, that the account will be deleted after the workshop, so if you want to save your project you will need to connect to your github or download it.
You can access the BTP subaccount here
The logon credentials will be provided by the workshop hosts.

As you can see, AdminServiceAddressHandler defines a handler for an incoming messaging event which is responsible for the addresses replication from the remote service to the local persistence. Since in our case the remote service does not emit any events, we can use the Developer Dashboard to simulate the BusinessPartnerChanged event to test the implementation.
You can open the Developer Dashboard via the Welcome Page of the Java Application:
Open the Dashboard UI link to get in:
In the messaging section of the dashboard, we see the bupa-messaging service, which offers a subscription to our BusinessPartnerChanged event:
Click on the RECEIVE button and set the BusinessPartner to 10401010:
Finally confirm and you will find the logs of the custom handler in the dashboard console:
You can now check whether the data has been persisted in the persistence section of the dashboard:
In some cases, we want to see if the outbox is configured correctly and the events in the outbox are processed asynchronously. Since the audit log events are processed by the outbox, we can trigger them by fetching the books list in the Browse books action of the application:
In the outbox section, you will find in the outbox history the audit log event that was processed by the outbox. You can repeat it or create a new custom outbox event to see how it behaves:
