I am comparing the costs of upkeep for 2 assets.
In the alternate states [Compare 1] and [Compare 2] I select which 2 assets.
I have a chart each associated with the alternate states.
In my expression I have.
sum({[Compare 2] <AA = [Compare 1]::AA , MAT_ItemNum = {"9*"}>} Mat_Cost)
AA is a "transaction" dimension that holds values such as "material", "Labour"...
This expression work fine.
When I replace the "AA" with a variable the expression throws an error from [Compare 1]....
sum({[Compare 2] <$(vWhichFilter) = [Compare 1]::$(vWhichFilter), MAT_ItemNum = {"9*"}>} Mat_Cost)
Can someone help me with the syntax of this or is this approach simply not possible/wrong?
