During ATC execution, the central check system accesses the systems in your landscape remotely through so-called remote stubs using RFC connection. Thus, remote stubs serve as an interface between the central check system and on-premise systems; they return a model of custom code that needs to be checked.
In the on-premise system, implement SAP Note 2599695 (Custom Code Migration Fiori App: Remote Stubs for the Checked System) in advance.
You want to analyze your custom code in your on-premise system using the Custom Code Migration app.
