• What is the cause and solution for SAP error message SWDP_WB_TOOL032 - You can only delete event handlers using action/inbound plug ?

  The SAP error message SWDP_WB_TOOL032 indicates that you are trying to delete an event handler in the Web Dynpro ABAP environment, but the action you are attempting is not allowed in the current context. Specifically, this error occurs when you try to delete an event handler directly from the event handler list without using the appropriate method (action/inbound plug).

  Use the Correct Method:
  
  Navigate to the Action or Inbound Plug that is associated with the event handler you want to delete.
  Open the properties of the action or inbound plug.
  Look for the event handler you want to remove in the list of event handlers.
  Use the provided option to delete the event handler from there.
  
  
  
  Save and Activate: After making the changes, ensure you save and activate your Web Dynpro component to apply the changes.
