  Cause:
  This warning message occurs when a date or time value entered or processed in the system does not exist or is invalid. Common reasons include:
  
  Entering a date that is outside the valid range defined in the system.
  Using a date format that is not recognized or incorrectly formatted.

  Solution:
  
  
  Check the Date/Time Format:
  
  Ensure the date and time are entered in the correct format as per the system settings (usually DD.MM.YYYY or YYYY-MM-DD).

  Check if the date is within the allowed posting periods or fiscal year variant.
  
  
  
  Check Factory Calendar:
  
  If the date relates to scheduling or planning, verify that the factory calendar includes the date.

  System Settings:
  
  Review system parameters related to date and time.
  Check user-specific settings for date/time format.
