In the Sales Department, a sale begins when a sales clerk receives a purchase order from a customer, which arrives in the form of paper. (Hint: this is your input.) (Hint: if you didn't use a start symbol, you should have.) The sales clerk checks to see if the customer has been established in the computer by selecting the Customer File in the computer. (Hint: ask question) (Hint: Customer File is storage.) If the customer does not exist in the system, a copy of the purchase order is sent to the credit department and the original purchase order is put in a pending file. No further work is done now. (Hint: you should terminate here.) If the customer does already exist in the system, the sales clerk proceeds to the next step. . The sales clerk enters item numbers and quantities. The computer looks up the item number in the Price File and calculates the cost for that item. (Hint: the Price File is storage. This step is repeated until all items have been entered. (Hint: this is a loop.) . . After the last item has been entered, 4 copies of the sales order are printed. The first copy is stapled to the front of the customer's purchase order is retained in a file cabinet in the sales department. Copy 2 is sent to the Warehouse so the items can be pulled and boxed. Copy 3 is sent to Accounts Receivable (as a control so no sales invoices can be prepared without a matching sales order). Copy 4 is sent to Shipping (as a control so no shipments can be made without a sales order) (Hint: you should have spit in 4 directions all ending with a terminator.)
