Denied

This tab contains all orders that have been denied. The denial can happen at any stage of the order processing (see above), so it is advisable to enter comments regarding the reason for the denial. A denied order cannot be restored or otherwise processed in any way. The reserved inventory has bee released at the time the order was denied, and there is no way to undo that. However, if you need to fulfill a denied order, you can clone it, creating a new order with the same information and Incomplete status. This new order can be processed as usual.
One action unique to this and Archives section is Delete. Only Denied and Archived orders can be deleted. Deleting an order permanently removes it from the database, and cleans up any references to the order. There is no way to retrieve the order information after it has been deleted (unless you have database backups, which you will need to analyze manually), and moreover, the order number of a deleted order can technically be reused for another order (normally this would not happen, because the system uses the highest order number to generate the next one, therefore “holes” in the sequence are not used up). All of this could cause historical inaccuracies and difficulties tracing order details. Therefore, we strongly recommend not to delete orders, unless it is necessary for some other purposes.
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.
• Deleted – permanently removed the selected order from the database.
• 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.
• Print – prints the order invoice.
