• What is the cause and solution for SAP error message WD418 - Function was canceled ?

  The SAP error message WD418: Function was canceled typically occurs in the context of Web Dynpro applications. It indicates that a function call or an action within the Web Dynpro component was canceled or did not complete successfully.
  
  Cause
  
  User Cancellation: The user explicitly canceled an operation or navigation.
  Timeout or Navigation Interruption: The function call was interrupted due to timeout or navigation away from the current view.
  Backend or Runtime Error: An error in the backend processing or in the Web Dynpro component logic caused the function to abort.
  Programming Issue: The Web Dynpro application code explicitly calls wd_this->cancel() or similar methods to cancel the function.
  Authorization Issues: The user lacks the necessary authorization, causing the function to be canceled.
  System or Network Issues: Communication problems between frontend and backend can cause the function to be canceled.
