Suprina Athlectic Supply Company specializes in selling sporting goods, gymnasium equipment and other athlectic supplies to high schools, colleges, and universities. Customers give their orders to the company's sales representatives at customer locations using the following procedures. At the customer locations, Suprina's sales representatives enter customer locations, Suprina's sales representatives enter customer orders on their computers where they are added to the daily orders file. Once entered, two copies of the order are printed and the sales rep gives copy 1 to the customer and retains copy 2 for his files. Suprina Athlectic Supply company sells in its Web site suprina-athletic.com. The company'ss IT infrastructure consists of a front-end Web server that interacts with customers and a back-end ERP system that manages the inventory and performs other typical ERP functions. The sales order process begins when a customer logs on to the suprina-athletic.com Web site. The Web server requests the current Suprina Athletic online catalog from the ERP system, which sends the catalog to the Web server, and the server displays it to the customer. The customer selects the items and quantities that he wants to purchase; the Web server edits the customer input for accuracy (e.g., ensures that all required fields have been selected or filled in) and sends this list on to the ERP system, where the requested quantities of inventory are allocated for the sale. The ERP sends back to the Web server the quantities that have been allocated, and the Web server displays this information on the customer's screen. The customer verifies that the order is correct and completes the sale by entering his shipping and credit card information. The Web server edits this data for accuracy (e.g., ensures that all required fields have been selected or filled in and that the length of the entered credit card number is correct) and sends the credit card information and amount of the sale on to the credit card company. The credit card company sends back a verification number, and the Web server notifies the customer that the sale has been completed by displaying a confirmation number on the customer's screen. At the end of each day, the laptop retrieves the day's orders and send them to the computer at Suprina headquarters. The computer calculates various totals, such as number of orders and numbers of line items on those orders, and records those totals with the orders in the customer order file. Each morning, the computer at Suprina headquarters displays the customer order fime (with totals) to the order entry clerk (also at Suprina headquarters). The clerk reviews the orders and compares the totals for each sales rep's orders with the overall totals that the computer has provided. After being notified by the clerk, the computer begins processing the customer orders by performing a series of programmed edits as follows. Data from the customer master file is accessed to validate customer name and address. The inventory master file is accessed to check for inventory availability and pricing. The customer's credit limit (from the customer master file) is then compared to the amount of the order, outstanding sales orders (sales order master file), and accounts receivable balances. If any orders fail these edits, the clerk is notified. Customer orders that pass these tests are then recorded on the sales order master file and the inventory balances are reduced. Two copies of the sales order are printed and sent to the customer (copy1, an order acknowledgment) and to the warehouse (copy 2, a picking ticket)
