  Review Allocation Settings: Check the configuration of product allocations in the system. Ensure that the settings allow for the consideration of past allocations if that is a requirement for your business process.
  Adjust Time Periods: If your business process requires the use of past allocations, consider adjusting the time period settings in the ATP configuration to include past periods.
