ABC Inc. customers mail their orders to the customer service center where a clerk opens the orders and reviews the orders for accuracy. The clerk then keys orders into the computer. As the clerk is entering data the computer populates the order input screen with data from the applicable customer (drawn from customer master data) and the inventory master data. The computer displays the completed order and the clerk reviews the order and then accepts the order. The computer then adds the sales order into sales order master data, updates the inventory master data to allocate inventory to the sales order, prints a picking ticket in the warehouse, and displays the sales order number to the customer service center clerk. The clerk then reads this number to the customer.
