Optimize multiple variables in DAX IF statements

Hello,

 

I have a measure that captures the slicer value selected, then returns a specific scenario which rankx my data.

 

 

AlgoSelectivePINS = 
VAR _SlicerValueLow = 6
VAR _SlicerValueHigh = 7
VAR _ScenarioA =
    IF (
        HASONEVALUE ( Local[DISTRICT] ),
        CALCULATE (
            RANKX (
                FILTER ( ALL ( Local ), Local[SelectNoChina] = 0 ),
                FPins[PINS YTD YoY Δ]
            ),
            ALLEXCEPT ( Local, Local[DISTRICT] )
        ),
        "-"
    )
VAR _ScenarioB =
    IF (
        HASONEVALUE ( Local[DISTRICT] ),
        CALCULATE (
            RANKX ( FILTER ( ALL ( Local ), Local[SelectNoGP] = 0 ), FPins[PINS YTD YoY Δ] ),
            ALLEXCEPT ( Local, Local[DISTRICT] )
        ),
        "-"
    )
VAR _ScenarioC =
    IF (
        HASONEVALUE ( Local[DISTRICT] ),
        CALCULATE (
            RANKX ( FILTER ( ALL ( Local ), Local[SelectAll] = 0 ), FPins[PINS YTD YoY Δ] ),
            ALLEXCEPT ( Local, Local[DISTRICT] )
        ),
        "-"
    )
VAR _ScenarioD =
    IF (
        HASONEVALUE ( Local[DISTRICT] ),
        CALCULATE (
            RANKX ( FILTER ( ALL ( Local ), Local[SelectNone] = 0 ), FPins[PINS YTD YoY Δ] ),
            ALLEXCEPT ( Local, Local[DISTRICT] )
        ),
        "-"
    )
VAR _ScenarioSelectorA =
    IF (
        [SlicerCaptureSum] < _SlicerValueLow,
        _ScenarioB,
        IF ( [SlicerCaptureSum] < _SlicerValueHigh, _ScenarioA, _ScenarioC )
    )
VAR _ScenarioSelectorB =
    IF ( [SlicerCaptureSum] = _SlicerValueLow, _ScenarioD, _ScenarioB )
RETURN
    IF (
        'Biais Switch'[BiaisCaptureSum] = 0,
        _ScenarioSelectorA,
        _ScenarioSelectorB
    )

 

 

I would like to know if switching my HASONEVALUE() evaluation with instead a variable, such as VAR _DistrictValueCheck = HASONEVALUE(Local[DISTRICT]) would work better than having, for each scenario, the evaluation you see in my code above.

 

Thanks !

It would help a bit I think, the new VAR would only evaluate once as opposed to each time.  You should take a look at DAX studio which can help you judge the improvement you would see from the change.

It lets you modify and test measures locally in the tool without changing your model until you are ready.
