    • This new tool allows you to easily analyze a product and track the changes throughout the rules’ application process. Thanks to this feature you will know what happens to the attributes’ values for a given product as rules are applied.
    • How to use this tool?
      • On the Products page, a new icon image was added to each product allowing you to activate tracking for the following 24 hours.

      • When rules are being applied, Mergado will track and save changes made by those rules to products that have the tracking enabled.

      • There are two ways to preview the results:

        1. By clicking the icon for a given product on the Products page you can preview changes from the last rules’ application.
        2. All changes are available to preview by clicking a particular record from the rules’ application on the History page.
