Hi,
The Exclude Extreme Values flag applies to activities with Revenue and Engagement metric types only. Analytics for Target (A4T) Primary Goal and Additional Metrics only support Conversion or Analytics metrics.
For activities with Revenue and Engagement metric types:
To exclude extreme values from your reports:
Open an activity that includes Revenue or Engagement metric types, then click the Reports tab.
Click the gear icon ( ) to display the Report Settings options.
Toggle the Exclude Extreme Values option on or off, as desired.
Click Save Settings.
Hope this helps!
