  Solution:
  
  Review Requirements: Check the requirements that are causing the error. Identify the orders or requests that have past dates and determine if they need to be updated or canceled.
  Update Dates: If the requirements are still valid, update their requested delivery dates to a future date.
  Check Configuration: Review the ATP configuration settings in your SAP system to ensure they are set up correctly. This includes checking the planning horizon, lead times, and rescheduling rules.
  Run ATP Check: After making necessary adjustments, run the ATP check again to see if the error persists.
