This typically occurs in the context of production planning or maintenance planning where cycles are used to define repetitive tasks or processes.
  Cause:
  
  Missing Cycle Unit: The primary cause of this error is that the cycle unit, which is necessary for the cycle to function correctly, is not defined or is missing in the system.
