VALUES function with HASONEVALUE and SUMX iterator function

[Sania-F]

sales commission iterator =

SUMX(

    VALUES('Sales Territory'[Region]),

    CALCULATE(

        [Revenue]

        * IF(

            VALUES('Sales Territory'[Country]) = "United States",

            0.15,

            0.1

        )

    )

)
----------------------------------------------------------------------------------

sales commission = [Revenue] *

if(HASONEVALUE('Sales Territory'[Country]),

 IF(VALUES('Sales Territory'[Country]) = "United States", 0.15,0.1))

• Iterator version = correct when multiple values exist, because it loops through each row and applies the right logic.

• Simple version = works only when the filter context guarantees one country at a time. If multiple exist, it miscalculates.

• In sales commission iterator, SUMX iterates through each region, evaluates [Revenue] * 0.1, then sums up.

• In sales commission, you’re multiplying the total [Revenue] in context by 0.1.

Rule of thumb:

• Use simple measure if your business rule applies a single rate per filter context.

• Use iterator (SUMX) when you need row-by-row logic, e.g., different commission rates for different countries/products.
