Error Using a Dax Measure as a constant

[CarlosPelay]

Hi I have a dash with a number of measures filtered by the current fiscal year. 

I'd like to save the value of the current fiscal year in a Dax measure and then use that measure as a sort of constant to filter all my other measures.  That way I only have to update the value of the one constant measure every year instead of all the other measures.

For example:

__CURRENT CAMPAIGN YR = "FY25"

and then

Appeals_Total$_SPONSORSHIP = CALCULATE(SUM('Final_RE_Gift Detail'[Appeal Split Amount]),'Final_RE_Gift Detail'[Appeal]="BBFC Sponsorship",'Final_RE_Gift Detail'[Campaign]=[__CURRENT CAMPAIGN YR])

But this gives me the following error:

However, this works:

Appeals_Total$_SPONSORSHIP = CALCULATE(SUM('Final_RE_Gift Detail'[Appeal Split Amount]),'Final_RE_Gift Detail'[Appeal]="BBFC Sponsorship",'Final_RE_Gift Detail'[Campaign]="FY24")

Any suggestions as to how I can implement this correctly?

Thank you.

Thanks for the reply from lbendlin.

Hi @CarlosPelay,

As lbendlin says, when we try to use a measure as a filter in another measure, a syntax error occurs because the measure cannot be calculated as a fixed constant value.

To solve this problem, we can use a variable in the second measure to store the value of __CURRENT CAMPAIGN YR.

Please use the following DAX:

Appeals_Total$_SPONSORSHIP = 
VAR _a=[__CURRENT CAMPAIGN YR]
RETURN
CALCULATE(SUM('Final_RE_Gift Detail'[Appeal Split Amount]),'Final_RE_Gift Detail'[Appeal]="BBFC Sponsorship",'Final_RE_Gift Detail'[Campaign]=_a)

Thanks Zhu!  This was very helpful

You cannot measure a measure directly. Either materialize it first, or create separate measures that implement the entire business logic.
