Is it possible to update or delete the order items from the order with out creating the new order?

Question

In my case, an order should be modified after the review. Order items can be removed or quantity will be modified from the order.

I knew the Re order would the do the purpose by manually deleting the old order once re order is completed. But I do not want to change the order id.

Answer 1

It too bad idea to change order item and order details,delete order after order placed.As per as magento system ,there lot of calculation like grand total,subtotals,tax,shipping cost are depends on order items.

If you will done any change at order items and delete items then it will create huge issues on calculation sales.

So it will better idea to you create an new order for this case and cancel old order.
