Why using CALCULATE(SUM()) ?

[Anonymous]

I see often measures written as:

Measure CY:=

CALCULATE(

    SUM('Table'[Col])

)

What’s the use of CALCULATE there?

Shouldn’t it just be written as Measure CY:=SUM('Table'[Col])

(I want to rewrite them as the latter form, but I wanted to be sure first...)

When you create a new measure, you do not need to warp your formula with CALCULATE as any measure default is wrapped within a CALCULATE function so you can just write:

CY:=SUM('Table'[Col])
