To copy quote item fields to sale order item fields, we need to declare these fields in fieldset.xml


<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    <scope id="global">
        <!-- Copy quote to sale order fields -->
        <fieldset id="sales_convert_quote">
            <field name="custom_attribute">
                <aspect name="to_order" />
        <!-- Copy quote item to sale order item fields-->
        <fieldset id="quote_convert_item">
            <field name="manufacturer">
                <aspect name="to_order_item" />


Seem that we need to use Observer sales_model_service_quote_submit_before to assign the new fields:

  • i am using same way but not working for me ! <fieldset id="sales_convert_quote"> <field name="custom_attribute"> <aspect name="to_order" /> </field> </fieldset> Oct 3, 2018 at 11:38
  • I want copy data 'quote_item' table filed 'test' to 'sales_order_item' field 'test' so how is it possible ? Oct 6, 2018 at 6:23

On 2.1.3 at least, doing it through fieldset.xml does not work.

I had to use the event sales_model_service_quote_submit_before , which is fired in function submitQuote of Magento\Quote\Model\QuoteManagement


                    'order' => $order,
                    'quote' => $quote
