  When does it occur?
  
  When a Web Dynpro application tries to display or process a workflow task but cannot find the corresponding task.
  During task processing in workflow scenarios.

  Confirm that the task is created and assigned properly.
  Make sure the task is active and not deleted.
  
  
  
  Check Task Assignment:
