Processed

This tab contains all processed orders. Orders here have been completed and closed, so there is not much more to be done with them. Depending on your procedures, you may want to archive them at certain intervals, not to overload this section with too many orders (this does not affect the performance of the system, but having lots of pages to scroll through may complicate managing of the orders).
This section has the following action buttons in the toolbar:

• Edit – edits the selected orders (as with any other list in In-portal, you can edit multiple items at once). You can only edit the administrator comments at this stage.
• Clone – creates a complete copy of the order, but assigns it a new order number, resets the status to “Incomplete” and clears any shipping dates and payment receipt confirmations. This is very useful for re-ordering – creating new orders for the same products to the same customer, as well as modifying orders when they have already been processed – to do this, clone the order and deny the original.
• Archive – archives the order (see manual for details about the archives)
• Print – prints the order invoice.
