Sales clerks prepare LCC charge slips and then all sales - cash and charge - are keyed into the cash register. At the end of the shift, the clerk forwards the LCC slips to the store cashier (ignore the handling of cash). The store cashier batches the LCC slips and sends the batches to the cash receipts section in Boston at 5:00 P.M. each day. As each sale is keyed in by the sales clerks, Lansdowne's central computer system captures the transaction data and stores them on a disk file. Each night, the computer prints a sales report summarizing each store's transaction data. On the following morning, the sales report is sent to the cash receipts section, where the LCC slips for each store are reconciled to the line on the sales report that totals LCC sales for that store. The LCC slips are then sent to data processing, where data preparation clerks enter the charges on a key-to-disk unit (this is not a computer peripheral - just show a keyboard and a disk in data processing in the flowchart). At 9:00 P.M. each evening, the disk transaction file created by data preparation is sent to the computer room, where it is used to update the accounts receivable master file (also on disk). Each month, the computer prepares customer statements that summarize the LCC charges, and sends the statements to the customers.
