  Key Concepts: 
  An event handler is a programming construct in SAP's BC-WD Web Dynpro component that allows developers to define how the application should respond to user interactions. It is used to define the behavior of the application when a user interacts with it, such as clicking a button or entering data into a field. 
  
  How to use it: 
  Event handlers are created by the developer in the Web Dynpro component. They are triggered when a user interacts with the application, such as clicking a button or entering data into a field. The event handler then defines how the application should respond to that interaction. For example, if a user clicks a button, the event handler can be used to define what action should be taken when that button is clicked. 
  
  Tips & Tricks: 
  When creating an event handler, it is important to consider how the application should respond to different types of user interactions. For example, if a user clicks a button, what action should be taken? Should the application open a new window or display an alert message? It is also important to consider how the application should respond if an error occurs during the user interaction.
