  Key Concepts: 
  Event interception is a feature of the BC-WD Web Dynpro component of SAP. It allows developers to intercept events that are triggered by user actions, such as clicking a button or entering data into a field. This allows developers to customize the behavior of the application in response to user input.
  
  How to use it: 
  Event interception can be used to customize the behavior of an application in response to user input. To use event interception, developers must first create an event handler for the event they wish to intercept. This event handler will contain the code that will be executed when the event is triggered. Once the event handler is created, it must be registered with the application so that it can be triggered when the user performs the action associated with the event.
  
  Tips & Tricks: 
  When using event interception, it is important to ensure that the code in the event handler is optimized for performance. This will ensure that the application responds quickly and efficiently to user input. Additionally, it is important to consider how different events may interact with each other and how they may affect the overall behavior of the application.
