  Cause:
  
  Invalid Date: The date you are trying to use for a transaction (like production order, goods movement, etc.) falls outside the valid dates defined in the factory calendar.
  Factory Calendar Settings: The factory calendar may not be set up correctly, or the specific period you are trying to access may have been closed or is not active.

  Navigating to the period closing settings in the controlling module.
  Transaction Code: OKP1 (for opening periods in controlling).
