Funnel's Data Studio connector now automatically deduplicates field names within views.
Having multiple fields with the same name can make it hard to navigate your data within Google Data Studio. This new feature will automatically append the source of the field to the name when you have multiple fields with the same name within a Data Studio view.
For example, if you have Cost from Criteo, Dianomi, and our custom Cost field they will be called 'Cost (Criteo)', 'Cost (Dianomi)' and 'Cost'. Other fields that are not duplicates will not be changed.
Please note that in order for this to have affect on your existing Data Studio connection you need to use the Refresh Fields feature within Google Data Studio.
