  Key Concepts: 
  APC handler class is a type of class in the ABAP Runtime Environment (BC-ABA) of SAP. It is used to handle asynchronous processing requests (APC) from the SAP system. An APC handler class is responsible for processing the request, and then returning the result to the caller. 
  
  How to use it: 
  To use an APC handler class, you must first create a class in the ABAP Runtime Environment (BC-ABA). This class must implement the interface IF_APC_HANDLER. This interface defines the methods that must be implemented by the APC handler class. Once the class is created, it can be registered with the SAP system using the transaction code SM30. 
  
  Tips & Tricks: 
  When creating an APC handler class, it is important to ensure that all methods defined in the IF_APC_HANDLER interface are implemented correctly. This will ensure that the APC handler class works as expected when processing requests from the SAP system.
