Checkout page it displays order summary section.It has Product data displaying .Product infromation coming from Magento\Checkout\Model\DefaultConfigProvider.php and from getTotalsData() function if it is in shipping step and when I switch in payment step order summary section display product information but it is not coming from getTotals() in payment section.

If I change code from $output['totalsData'] = $this->getTotalsData() to $output['totalsData'] = array() in getConfig() function so result is order summary product section not display in checkout shipping step but it displays in payment step

I have added following code in file: pub\static\frontend\Magento\luma\en_US\Magento_Checkout\template\summary\item

<pre data-bind="text: ko.toJSON($parent, null, 2)"></pre>

And display following result in checkout page:- I have changed code in getTotalsData() function in Magento\Checkout\Model\DefaultConfigProvider.php path and add isbn attribute in totalsdata object but not diplay in payment step but it display in shipping step

Shipping Step 1: http://i.stack.imgur.com/hFV0t.jpg This above shipping step screenshot where it display totals information and also display my custom product attribute 'isbn'.

Payment Step 1: http://i.stack.imgur.com/GlIe7.jpg This above shipping step screenshot where it display totals information and not display my custom product attribute 'isbn'.

I have changed in core file DefaultconfigProvider.php temporary to check

And changed only this getTotalsData() function

private function getTotalsData()
        /** @var \Magento\Quote\Api\Data\TotalsInterface $totals */
        $totals = $this->cartTotalRepository->get($this->checkoutSession->getQuote()->getId());
        $items = [];
        /** @var  \Magento\Quote\Model\Cart\Totals\Item $item */
        foreach ($totals->getItems() as $item) {
            $data = $item->__toArray(); // custom code
            $data['isbn'] = 'ISBN-12345'; // custom code
            $items[] = $data;
        $totalSegmentsData = [];
        /** @var \Magento\Quote\Model\Cart\TotalSegment $totalSegment */
        foreach ($totals->getTotalSegments() as $totalSegment) {
            $totalSegmentArray = $totalSegment->toArray();
            if (is_object($totalSegment->getExtensionAttributes())) {
                $totalSegmentArray['extension_attributes'] = $totalSegment->getExtensionAttributes()->__toArray();
            $totalSegmentsData[] = $totalSegmentArray;
        $totalsArray = $totals->toArray();
        if (is_object($totals->getExtensionAttributes())) {
            $totalsArray['extension_attributes'] = $totals->getExtensionAttributes()->__toArray();
        return $totalsArray;

You can set your custom attribute inside checkout page summary block using below way,


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">    
    <!-- Set Custom attribute in chekcout page summary block -->
    <type name="Magento\Checkout\Model\DefaultConfigProvider">
        <plugin name="default_config_provider" type="Package\Module\Model\DefaultConfigProvider"/>

app/code/{Package}/{Module}/Model/DefaultConfigProvider.php file

namespace Package\Module\Model;

use Magento\Checkout\Model\Session as CheckoutSession;
use Magento\Quote\Api\CartItemRepositoryInterface as QuoteItemRepository;

        QuoteItemRepository $quoteItemRepository,
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    ) {
        $this->_scopeConfig = $scopeConfig;
        $this->checkoutSession = $checkoutSession;
        $this->quoteItemRepository = $quoteItemRepository;

    public function afterGetConfig(\Magento\Checkout\Model\DefaultConfigProvider $subject, $result)
        $quoteId = $this->checkoutSession->getQuote()->getId();
        if ($quoteId) {            
            $itemOptionCount = count($result['totalsData']['items']);

                $isbnOptions[$quoteItemId] = $quoteItem['isbn'];               

                $quoteParentId = $result['totalsData']['items'][$i]['item_id'];

                    foreach($newOption as $key=>$value){
                        if( !is_array($value) ){
                            $currentOption[] = array('value'=>$value,'label'=>$key);
                    $result['totalsData']['items'][$i]['options'] = json_encode($currentOption);
        return $result;
