An operator checks whether a certain cleaning service is urgent service or a standard finishing date service, and in the case of urgent service, the ECR judges whether there is a margin for the weighted quantity of commodities received from the costomer or not based upon the table, and when there is a margin, determines the latest period as a cleaning processing date.
