Make advanced e-commerce?

Question

Google Analytics

It is necessary to set up advanced e-commerce through TGM for YM and GA
0) dataEcommerce in this form

1) I pass the array $data//dataEcommerce to TGM

<script>dataEcommerce = [<?=json_encode($data)?>];</script>
<!-- Google Tag Manager -->
    <noscript><iframe src="//www.googletagmanager.com/ns.html?id=<?=Configure::read('GoogleTagManager')?>"
                      height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
    <script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
            new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
            j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
            '//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
    })(window,document,'script','dataEcommerce','<?=Configure::read('GoogleTagManager')?>');</script>
<!-- End Google Tag Manager -->

2) tag for YM set up like this

<!-- Yandex.Metrika counter -->
<script type="text/javascript">
    (function (d, w, c) {
        (w[c] = w[c] || []).push(function() {
            try {
                w.yaCounter32547095 = new Ya.Metrika({
                    id:32547095,
                    clickmap:true,
                    trackLinks:true,
                    accurateTrackBounce:true,
                  	ecommerce: 'dataEcommerce'
                });
            } catch(e) { }
        });

        var n = d.getElementsByTagName("script")[0],
            s = d.createElement("script"),
            f = function () { n.parentNode.insertBefore(s, n); };
        s.type = "text/javascript";
        s.async = true;
        s.src="https://mc.yandex.ru/metrika/watch.js";

        if (w.opera == "[object Opera]") {
            d.addEventListener("DOMContentLoaded", f, false);
        } else { f(); }
    })(document, window, "yandex_metrika_callbacks");
</script>
<noscript><div><img src="https://mc.yandex.ru/watch/32547095" style="position:absolute; left:-9999px;" alt="" /></div></noscript>
<!-- /Yandex.Metrika counter -->

3) for GA tag set up like this

4) tags work on the page

But not in YM not in GA orders do not fall

Answer 1

I think that there are several implicit points that are little described in the counter documentation:

1. To transfer enhanced electronic commerce (EEC) to GTM, you must use not a transaction! Transaction - this is for the accounting of transactions for regular electronic commerce. And you need to use the page view with the transfer of data about the EEC. Read more here . Configuration: Tag type : Universal Analytics, Track type : Pageview, Enable Enhanced Ecommerce Features: true, Use Data Layer: true, Basic Settings - Document Path: {{url path}}, Firing Rule: {{event}} equals gtm. dom
   
2. If you want to use not dataLayer, but something else, then the setting looks something like this. You just need to substitute your variable passed to GTM
   
3. It is better to initialize a variable like this window.dataLayer = window.dataLayer || []; because it will not be overwritten with such initialization.
   
4. After these settings, data transfer to GA should work
   
5. For NM, the setting implies mandatory initialization of the variable https://yandex.ru/support/metrika/data/e-commerce.... followed by pushing data into it.
