The documentation for the EDP system consists of the following: record layouts, program listings, logs, and error listings. Once goods are shipped from one of Steeplechase’s three warehouses, warehouse personnel forward shipping notices to the accounting department. The billing clerk receives the shipping notice and accounts for the manual sequence of the shipping notices. Any missing notices are investigated. The billing clerk also manually enters the price of the item, and prepares daily totals (supported by adding machine tapes) of the units shipped and the amount of sales. The shipping notices and adding machine tapes are sent to the computer department for data entry. The computer output generated consists of a two copy invoice and remittance advice and a daily sales register. The invoices and remittance advice are forwarded to the billing clerk, who mails one copy of the invoice and remittance advice to the customer and files the other copy in an open invoice file, which serves as an accounts receivable document.
