  Error Message
  WD284 No subsequent function found for selected event
  
  Cause
  This error occurs in the Web Dynpro ABAP environment when an event is triggered, but the Web Dynpro application cannot find a corresponding subsequent function (i.e., an event handler or action method) to process that event.
  In Web Dynpro, UI elements (like buttons, links, etc.) trigger events. These events must be linked to event handler methods in the component or controller. If the event is fired but no handler is assigned or the handler is not implemented, the runtime raises this error.
  Common causes include:
  
  The event is declared in the interface but no handler method is assigned.
  The event handler method exists but is not properly linked in the Web Dynpro component/controller.
  The event handler method is missing or incorrectly named.
  The event is triggered programmatically but no subsequent function
