  Time Constraints: If the planned start or finish times of operations conflict with other scheduled activities or if there are time overlaps, this can trigger the error.
  
  
  Missing or Incorrect Dates: If the dates for the production order or the planned order are not set correctly, it can lead to scheduling issues.
