    Hey @Rapidstudent,

    I am not aware of a straightforward way to have a grouped rank attribute, but, you can achieve this by utilizing the loop values operator that loops over unique values, which is not much of a hassle aswell. Check out the mock XML of how the process would look like below.

    <?xml version="1.0" encoding="UTF-8"?><process version="9.6.000">
      <operator activated="true" class="process" compatibility="9.6.000" expanded="true" name="Process">

    My way would be:
    Group Into Collection by ShopId, Loop Collection, Sort (by totalsale) and append it again.

    This requieres operator toolbox extension.
