Leverage INTERSECT to apply relationships in DAX

If you are used to virtual relationships in DAX (see Handling Different Granularities in DAX), you probably use the following pattern relatively often:

[Filtered Measure] :=
CALCULATE(
    <target_measure>,
    FILTER(
        ALL(<target_granularity_column> ),
        CONTAINS(
            VALUES(<lookup_granularity_column> ), 
            <lookup_granularity_column>,
            <target_granularity_column> 
        )
    )
)

In the new DAX available in Excel 2016*, Power BI Desktop, and Analysis Services 2016, you can use a simpler syntax, which offers a minimal performance improvement and is much more readable:

[Filtered Measure] :=
CALCULATE(
    <target_measure>,
    INTERSECT(
        ALL(<target_granularity_column> ),
        VALUES(<lookup_granularity_column> )
    )
)

You can find a longer explanation of this new pattern and download some examples in the new article Physical and Virtual Relationships in DAX, on SQLBI web site.
