Dual Dynamic KPI's are generally used to represent two metrics/measures at a time in an insight as a primary and secondary measure. Meaning, we can compare two metrics in a single KPI.
For example, I created dual dynamic KPI showing year wise total profit in the primary measure and the growth precentage in the secondary measure.
Attached are the two screenshots for your reference.
Screenshot1: Represents dual dynamic KPI insight showing profit TY & growth percentage.
Screenshot2(For reference) : Tabular form representation of year wise Profit TY , Profit LY and growth precentage.
Now compare growth percentage in both screenshots you will get to know what is the use of this insight.
