1. The mailroom receives customer orders from customers, where clerks sort orders from the rest of the mail, group them into batches, prepare a transmittal sheet, and forward the orders and the transmittal sheet to the order entry department.
A clerk in order entry first checks that the batch is complete. The clerk looks up the customer number in a customer list and then keys the essential customer information into a network computer. The computer then checks the customer file, which is stored on disk, to see that the customer exists and has an acceptable credit record. The computer displays the approval of the customer on the order entry clerk’s computer terminal. The clerk then keys in the rest of the order.
The computer logs the order in a sales order transaction file, which is stored on tape. At the end of the day, the computer processes the tape against the customer file and prints a picking ticket, a sales order notification, and a vendor acknowledgement. The computer sends the picking ticket to the warehouse, the sales order notification to the shipping department, and the vendor acknowledgement to the mailroom. At this time, the computer also records the sales order in the sales order master file (a disk file).
The warehouse clerk assembles the customers’ orders (using the picking ticket). Then he forwards the completed orders (just show the picking ticket) to the shipping department. The shipping clerk compares the the picking ticket to the sales order notification. After the clerk keys the sales order number into the computer, the computer accesses the sales order master file and displays the order on the shipping clerk’s computer screen. The shipping clerk keys in the items and quantities being shipped and enters a code to accept the shipment. Once the clerk has accepted the shipment, the computer updates the sales order master file. The computer prints a packing slip and bill of lading on a printer in the shipping department. 1 2 3 4 5 6 7 8 10 11 9 12 13 14 15 16 21 22 23 24 17 18 26 25 19 20
