There is custom field in quote_item table same as sales_order_item both column name and type are same.

I want to convert quote_item table to sales_order_item table. so I have used fieldset.xml to convert those data,

my fieldset.xml file is,

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:DataObject/etc/fieldset.xsd">
<scope id="global">
    <fieldset id="quote_convert_item">
        <field name="customcolumn1">
            <aspect name="to_order_item" />
        <field name="customcolumn2">
            <aspect name="to_order_item" />

but its not working so strange

  • That configuration should be enough try to clean all var/generation and var/di and cache. and as @David Verholen said, debug your data there. Feb 10, 2016 at 6:30
  • I think you have to create plugins for the quoteItem:getExtentionAttributes and quoteItem:set ExtentionAttribute, the same for the orderItem, so that getDataFromFieldset to work. Dec 23, 2021 at 17:43

In Magento 2 without using fieldset you can also copy custom data from quote item to order item by using plugin.

create di.xml in your module etc folder.


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">
    <type name="Magento\Quote\Model\Quote\Item\ToOrderItem">
        <plugin name="cedapi_quote_to_order_item" type="Vender\Yourmodule\Model\Plugin\Quote\QuoteToOrderItem"/>

Create a class to your module and define a function. app/code/Vender/Yourmodule/Model/Plugin/Quote
Create QuoteToOrderItem.php file

namespace Vender\Yourmodule\Model\Plugin\Quote;

use Closure;

class QuoteToOrderItem
     * @param \Magento\Quote\Model\Quote\Item\ToOrderItem $subject
     * @param callable $proceed
     * @param \Magento\Quote\Model\Quote\Item\AbstractItem $item
     * @param array $additional
     * @return \Magento\Sales\Model\Order\Item
     * @SuppressWarnings(PHPMD.UnusedFormalParameter)
  public function aroundConvert(
        \Magento\Quote\Model\Quote\Item\ToOrderItem $subject,
        Closure $proceed,
        \Magento\Quote\Model\Quote\Item\AbstractItem $item,
        $additional = []
    ) {
        /** @var $orderItem \Magento\Sales\Model\Order\Item */
        $orderItem = $proceed($item, $additional);//result of function 'convert' in class 'Magento\Quote\Model\Quote\Item\ToOrderItem' 
        $orderItem->setCustomDesign($item->getCustomDesign());//set your required
        return $orderItem;// return an object '$orderItem' which will replace result of function 'convert' in class 'Magento\Quote\Model\Quote\Item\ToOrderItem'

On your fieldset, try this:

<fieldset id="sales_convert_quote_item">

instead of what you currently have:

<fieldset id="convert_quote_item">

I think the converting is done here: https://github.com/magento/magento2/blob/2.0/app/code/Magento/Quote/Model/Quote/Item/ToOrderItem.php#L61

you may want to debug here and see what happens


had the same problem today. It seems to be a bug since the converting itself seems to work, but the populeateWithArray then strips the new attribute.

I solved it with an around plugin on the ToOrderItem class like described here


In Magento\Quote\Model\Quote\Item\ToOrderItem::convert() After

    $orderItemData = $this->objectCopyService->getDataFromFieldset(

The $orderItemData contains the data of the custom field that you declare in fieldset.xml

But after that Magento create order item by Magento\Sales\Api\Data\OrderItemInterfaceFactory and set data of $orderItemData to it

    $orderItem = $this->orderItemFactory->create();
        array_merge($orderItemData, $data),

They will ignore custom fields that didn't define in OrderItemInterface


Try to create observer of sales_model_service_quote_submit_before and there get the object of order using $order=$observer->getOrder(); and set your values on that order object. it will solve your problem.

==== Update======
create events.xml and put the following code

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/Event/etc/events.xsd">
    <event name="sales_model_service_quote_submit_before">
        <observer name="event_name" instance="Companyname\Packagename\Observer\Observername" />

now create observer file Observername.php add this code

public function execute(\Magento\Framework\Event\Observer $observer)
