Measure totals don't sum correctly

[IntaBruce]

I have a measure which selects values using two other measures depending on a third measure.

Measures are: Actual Days, Potential days and Latest Actuals Period.  Actual days is only available up to the current period because after that is the future.  So my measure is as follows:

Forecast Days = VAR Period = SELECTEDVALUE(Allocations[Period])

RETURN

 IF(Period <= [Latest Actuals Period], [Actual Days], [Potential days])

At first glance this appears to work and returns the correct values but then the totals don't add up and the forecast days only totals the same as the Actual days.  See here:

What have I done wrong?

Thank you

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Hey @IntaBruce ,

consider wrapping SUMX around your existing expression like so:

measure = 
sumx(
    values(<the column you are using on the rows of the matrix visual>)
    , <your expression>
)

Hopefully, this helps to tackle your challenge.

Tom
