Avoid decrease of product quantity when the order status is still "Process"

[winresh24]

How to avoid decreasing of a product quantity when it's still in the "Process" and update when

the order was shipped or delivered? Anyone Could help me with this?

 

Right now I add this

 $id_order_state != Configuration::get('PS_OS_PREPARATION')

 in the statement of checkProductStock in OrderDetail.php and yes it doesn't decrease the quantity but when the order

was shipped and delivered it doesn't change too.

 

  

protected function checkProductStock($product, $id_order_state)

    {

        if ($id_order_state != Configuration::get('PS_OS_CANCELED') && $id_order_state != Configuration::get('PS_OS_ERROR') && $id_order_state != Configuration::get('PS_OS_PREPARATION')) {

            $update_quantity = true;

            if (!StockAvailable::dependsOnStock($product['id_product'])) {

                $update_quantity = StockAvailable::updateQuantity($product['id_product'], $product['id_product_attribute'], -(int)$product['cart_quantity']);

            }



            if ($update_quantity) {

                $product['stock_quantity'] -= $product['cart_quantity'];

            }



            if ($product['stock_quantity'] < 0 && Configuration::get('PS_STOCK_MANAGEMENT')) {

                $this->outOfStock = true;

            }

            Product::updateDefaultAttribute($product['id_product']);

        }

    }

Thanks

Have you solved the problem?

this requires modification of prestashop core, especially order status (orderhistory) change function where it will be necessary to add code to decrease item stock when you will select some order states.

How could I found out when the stock it's decreased ? On which of order states ?
