Users can setup recurring batch jobs for the "Inventory aging report storage", "Inventory on-hand report storage" and "Inventory value report storage" features but there isn't any type of recurring cleanup for this data. It would be helpful if the jobs had options to delete data that was more than a certain number of days old or if there were separate jobs that could be configured and schedule to delete the old data. Otherwise users have to go in and delete it periodically to prevent the tables from growing very large with old unused data.
