Moving Avergae of a calcualted column
2 February, 2016
Analytical function Date Column has been assigned a parameter field that is no longer valid.
The calculated column is using a subquery column and sum aggregation I don't know if that makes a difference
Unscheduled Removal Rate (URR) = ( Unscheduled Removals * 1000 ) / Hours Flown by Fleet in Report Month
Unscheduled Removal is a sum from the subquery .
The 3 Month Moving average on the URR is what is causing the problem any ideas ?
