I want to update the ordered product quantity from the sales order view page (admin side). I have added a new button and actions for update order quantity. But I don't know what are the tables needs to updated for this. or else is there any other solution?(without creating new order concept).
I already gone through below one.
Thanks
sales_flat_order_item
.$order->getAllItems();
and do something like$item->setQty(123);
in a foreach?
