Hi,

 

i have a issue about my dax measure.

all is right, but the total multiplie total quantity (costeTotalTarLY) by average cost (Avg C.Und LY) and i need a sum of total. The total was be around 550.000 but is 3.109.896

try this

Measure =
VAR __Summary =
    ADDCOLUMNS (
        SUMMARIZE ( 'Table', 'Calendar'[YearMonth] ),
        "Quantity CY", CALCULATE ( SUM ( 'Table'[Quantity] ) ),
        "Avg Cost LY", [Average Cost LY]
    )
RETURN
    SUMX ( __Summary, [Quantity CY] * [Avg Cost LY] )

the total is alignes with your logic here

Can you add sample tables (in format that can be copied to PowerBI) from your model with anonymised data? Like this (just copy and paste into the post window).

Then i need to calculate a 1 measure Average of Cost LY (01/2018)
Then i need to multiplie Quantity this year (01/2019) by Average of Cost LY (01/2018) an sum. This sum is error.

you need to use SUMX here, e.g. with SUMMARIZECOLUMNS (with whatever is in the rows before the numbers you show)

right now PowerBI adds all rows and then multiplies
you want it to multiply and then add rows, SUMX can do that

Thanks, but I can't think of a way to do the truth.
