How to debug while testing RAP app in Customizing Tenant?

[Expert]

How to set a break-point in my created RAP app on the Customizing Tentant, since there is the data for testing. But access to the Customizing Tenant via Eclipse is not allowed (Business Role SAP_BR_DEVELOPER is not available there). So how can I see what my code is doing (and goes probably wrong) in the Customizing Tenant?

In order to test (set breakpoints etc.) in the RAP code of your app, you will need to use the development client only (080) where you have the ADT installed. You cannot use the code testing in the customizing client (100) as the ABAP environment is not embedded in this client.

In order to do testing with the data in the customizing client in the development tenant, it is required that you create the necessary org entities, configurations and data sets (either manually or using migration cockpit) in the development tenant. This is a mandate as customizing & data cannot be replicated between clients in Development/Starter system as of today.
