I am trying to do some dashboards based on a universe. The main measure I would LIKE to use is a ratio
Loss Ratio = Sum(Loss)/Sum(Earnings).
Unfortunately though, since it is a ratio which would need to be aggregated correctly, I cannot make it a measure and need to do it at the report level if I were using it in WebI.
However my main requirement is for dashboards, and this ratio is what I would mainly like to show against several dimensions. How do I accomplish this?
Is there some way of creating metrics, or specifying formulas(like measures) in creating a dashboard?
It is possible to have a ratio defined as an object in the universe to be used by AF.
Create the measure object as SUM(tableA.column)/SUM(tableB.column) in the universe. Add the AGGR=SUM text to the description field. This will tell AF that the measure object is already aggregated and AF itself will not try to aggregate the measure.
This does seem to work, but I am not sure. It still doesnt roll up in WebI. So I am thinking of using a variable or a formula in webi and using this object in case of dashboards.
