  Cause:
  
  Incorrect Date Entry: The start date for the requirement may have been entered incorrectly, leading to a date that is in the past.
  System Date Settings: The system date on the server or user terminal may be set incorrectly, causing valid future dates to be interpreted as past dates.

  Check Requirement Dates: Review the requirement in question and verify the start date. If it is indeed set in the past, update it to a valid future date.
  Adjust System Date: Ensure that the system date on the server and user terminal is correct. If it is incorrect, adjust it to the current date.
  Review Scheduling Logic: If the requirement is part of a larger scheduling process, review the logic and dependencies to ensure that all related tasks are scheduled correctly.
