Measures can either be configured in Measure Editor or using Advanced Configuration of a report. Measures created in Measure Editor can more easily be re-used in new reports, so if you wanted to re-use a measure originally created in a report's advanced configuration, you can do this by copying the measure configuration from the report to the Advanced Configuration tab of a new measure. This video walks you through that process.
Please note: This video was recorded with an older version of Watershed, so some features might look slightly different. The overall process remains the same.
