From In-Portal User Manual

General

On this tab, you will see the common order properties.

• Order ID – Internal, read-only system ID of the order. It is never entered by the store administrator.
• Number – this is the unique order number, auto-generated by the system. The format of the number is specified in the Output configuration section (see manual). The sub-order number signifies that this order is a part of a larger order; all parts will have the same main order number, and unique order sub-numbers. Each sub-order is an independent, standalone order that must be processed on its own. Note, that while you can modify the Order Number and Sub-number, they must remain unique. Also, the system uses the highest number to generate the next order number; so if you manually change it to skip some numbers, they will never be used automatically any more. Therefore, it is generally advised not to modify the automatic order number generated by the system.
• Status – this is a read-only field that displays the status of the order. To change the status, please use the action buttons in the toolbar outside of the edit mode. See order process description above.
• Date – this field contains order date and time (The date and time when the order was first created).
• Username – this field contains the user name of the user who placed the order, or Guest if the customer was not authenticated.
• User Comment – this field is reserved for future use.
• Admin Comment – this field is not shown anywhere on the front end. It is designed to store the store administrator’s private comments about the order. This field is always editable (for any order status).
