Upon receiving part two of the packing slip, the customer service clerk uses the packing slip to pull the matching sales order filed earlier in the open sales order file. The customer service clerk enters data from the matched documents for updating the sales order in the sales order transaction file in the ERP system as being shipped. The ERP system automatically generates and sends an email to the customer that the shipment is on its way. The customer service clerk then files the matched documents by customer name and then by date in the closed sales order file.
