  Changes in Production Orders: If there are changes made to production orders after backflushing has occurred, it can lead to discrepancies in the inventory and backlog records.
  Incomplete Backflush Process: If the backflush process was not completed correctly, it may result in backlogs being created or modified unexpectedly.
  Configuration Issues: Incorrect configuration in the production planning module or in the backflush settings can lead to this error.
  Material Availability: If materials are not available or if there are issues with the material master data, it can cause backlogs to be created or changed.
