We’ve had a number of recent enhancements on our dimension tab, including:

• Roll up dimensions at the campaign level:
  
  You can now roll up your dimension data at the campaign level, along with the previously available group, keyword, product group, dynamic target, creative, and audience level. This is a critical update in preparation for the release of Google’s Performance Max campaigns, as this campaign type does not offer ad group-level data.
  
  
• View dimension totals by hierarchy:
  
  At the bottom of the Dimensions grid, you'll see a Totals row, which operates the same as any other totals row. 
  
  In addition to the standard Totals row, you will sometimes see a row called Totals (Hierarchy) when data is being rolled up by campaign. This is to show you total metrics aggregated by campaigns, so you can easily discover if you have more metrics from campaigns. If your Totals (Hierarchy) value is larger than your Totals rolled up by group, this would indicate additional metrics available at the campaign level. For campaign types such as Google's Performance Max, which do not offer ad group-level data, this is an important way to view your data that may not be available at other levels of the hierarchy.

• Compare your dimension performance over time with dimension history:
  
  We recently introduced the ability to see the history of your dimension values or a combination of dimension values across multiple dimensions and dimension tags. Select up to three dimensions at once to compare their performance over time.
  
  Once your columns have been added and your roll-up has been set, hover over the columns until you see the three dots icon appear. This will appear next to the dimension value on any of the dimension columns you have added to the grid. Once it's visible, click the three dots icon and select History.
