This typically happens in the context of Advanced Planning and Optimization (APO) when the system tries to schedule a process or activity that falls outside the operational hours defined in the calendar settings.
  Cause:
  
  Calendar Configuration: The calendar settings in SAP APO may not be configured correctly, or the specific time period for the operation is not included in the active calendar.
