  SAP Error Message: WD203 - Define object type and event type
  
  
  Cause:
  The error WD203 occurs in SAP Web Dynpro applications when the system expects an object type and event type to be defined for an event handler, but these are missing or not properly specified.
  In Web Dynpro, events are triggered by UI elements or components, and these events must be linked to an event handler method. Each event handler is associated with an object type (the context or component controller) and an event type (the event that triggers the handler). If these are not defined, the system cannot bind the event to the handler, resulting in this error.
  Typical scenarios causing this error:
  
  Event handler method is created but the event type or object type is not assigned.
  Incorrect or incomplete event handler configuration in the Web Dynpro
