• Key Concepts: 
  RAP behavior extension is a component of the BC-ESI-RAP RESTful ABAP Programming Model. It allows developers to extend the behavior of existing services and create new services with custom logic. It is based on the concept of “behavior extension”, which means that developers can add custom logic to existing services without having to modify the underlying code. This allows for faster development and easier maintenance of services.
  
  How to use it: 
  RAP behavior extension can be used to extend the behavior of existing services or create new services with custom logic. To do this, developers must first define a service class that contains the custom logic. This class must then be registered in the RAP registry, which is a central repository for all registered services. Once registered, the service can be used by other applications or services.
  
  Tips & Tricks: 
  When creating a service class, it is important to ensure that it is properly documented and tested before being registered in the RAP registry. This will help ensure that the service works as expected and does not cause any unexpected errors or issues. Additionally, it is important to keep the service class up-to-date with any changes in the underlying code or logic.
