  SAP Error Message:
  WD202 Specify event for object '&'
  
  
  Cause:
  This error occurs in Web Dynpro when an event handler is expected but not specified for a UI element or component. Specifically, the message indicates that an event must be assigned to the object (e.g., a button, link, or other UI element) but hasn't been defined yet.
  In Web Dynpro, UI elements like buttons or links trigger events (e.g., onAction, onClick). If you create such an element but do not specify which event it should trigger or if the event handler method is missing, the system raises this error.
  
  When does it occur?
  
  When you create a UI element in the Web Dynpro component but do not assign an event handler to it.
  When the event handler method is not implemented or not linked properly.
  When the event is referenced but not defined in the component controller or view
