When you enter the customer order number you will see all order rows under the Rows tab, as well as a window where you can choose to delivery the entire order.
At the far right of the heading row, you will see a speech bubble if a message has been registered for the customer in the Update Customer procedure. The message will open when you enter the customer code. However, you can also open the message by clicking on the speech bubble.
