• What is the cause and solution for SAP error message WD602 - Event type & not defined ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WD602 Event type & not defined
  
  Cause:
  This error occurs in the Web Dynpro ABAP environment when an event is triggered in a component or controller, but the event type has not been defined or declared in the component's interface or the controller's event interface.
  In other words, the Web Dynpro runtime tries to handle an event (e.g., a button click or a custom event), but it cannot find the event definition because it was never created or properly declared in the component or controller.
  
  When does it typically occur?
  
  When you try to raise or handle an event that has not been declared in the interface.
  When the event name used in the code does not match any event defined in the component or controller.
  When the event interface is missing or incomplete.
  After importing or copying components without properly adjusting event definitions.
  
  
  Solution:
  
  
  Check Event Declaration:
  
  Open the Web Dynpro component or controller in the Web Dynpro Explorer.
  Go to the Interface tab.
  Verify that the event mentioned in the error message (the placeholder & will be replaced by the actual event name) is declared under the Events section.
  
  
  
  Define the Missing Event:
  
  If the event is missing, create a new event with the exact name that is being triggered.
  Save and activate the component/controller.
  
  
  
  Check Event Usage:
  
  In the code where the event is raised (e.g., wd_this->fire_<event_name>), ensure the event name matches exactly the event declared in the interface.
  Correct any typos or mismatches.
  
  
  
  Re-activate the Component:
  
  Sometimes, after changes, the component needs to be re-activated to update the metadata.
  
  
  
  Check Event Interface Implementation:
  
  If the event is part of an event interface, ensure that the interface is properly implemented and the event is declared there.
  
  
  
  Transport and Version Consistency:
  
  If the component was transported from another system, ensure that all related objects (including event interfaces) are transported and active.
