You can change this for metrics in the data source and report. If left as None in the data source, the default aggregation in reports is`Sum`.\n\nRelated resources\n-----------------\n\n- [About dimensions and metrics](/looker/docs/studio/model-your-data)\n- [What does the \"Unable to aggregate ratio metrics\" error mean?](/looker/docs/studio/what-does-the-unable-to-aggregate-ratio-metrics-error-mean)"]]
