You can edit the default actual, threshold, flex, and alert amounts by editing the measure source record. For your reference, these defaults are also displayed on every measure record. You can enter actual, threshold, flex, and alert override amounts for each atomic measure in the Edit Measure panel. Threshold and flex values are used by the graphical tools to indicate the red/yellow/green stop light indications.
Be sure to perform careful analysis before setting these visual indicators because some executives and managers may rely on the colors alone when making decisions based on what the colors represent. Alert thresholds are values that work in a manner similar to thresholds. However, they trigger alert information to appear on the Today page.
Whether you are adding a new measure or editing an existing one, the same fields are available for creating or changing a measure. For more information, see Adding and Editing Measures.
