This error indicates that there are no maintenance items (such as maintenance plans or tasks) assigned to the maintenance order or work order you are trying to schedule.
  Cause:
  
  No Maintenance Items Assigned: The primary cause of this error is that the maintenance order or work order does not have any maintenance items linked to it. This can happen if the order was created without specifying any tasks or if the maintenance plan does not have any associated items.
