how to multiply different columns with a dax measure

[Salma_00]

Hi,

So basically, what i want to do is multiply 3 columns within themselves the thing is for a row in column 1 it has to be multiplied with the set before the row in question for column 2 and the set of rows after the column in question for column 3, I don’t know if I explained my problem properly but basically this is what I want to do

       

for the first row

the middle

The last row  

For my dax measure I tried with the following command

But it gave me this error

For the ones that do not speak French it states that the context where I put earlier does not exist

My index column is a dax measure that I wrote to make calculation easy for me

Hi @Salma_00,

Can you share a complete sample? You can use dummy data. 

EARLIER can't have a DAX measure as parameter. You can change it into a calculated column.

hi, 

thank you for your reply

i tried to  do a calculated column but since my calculations involve other dax measures, my attempts weren't successful 

here is a sample of my data

Hi @Salma_00,

How did you do it? Your formula is fine in the Power BI. Please check it out here.

Column =
CALCULATE (
    PRODUCTX ( Tableau1, [1+R] ),
    FILTER ( ALL ( 'Tableau1' ), 'Tableau1'[Index] > EARLIER ( Tableau1[Index] ) )
)
    * CALCULATE (
        PRODUCTX ( 'Tableau1', [1+B] ),
        FILTER ( ALL ( 'Tableau1' ), 'Tableau1'[Index] < EARLIER ( Tableau1[Index] ) )
    )
    * [allocation]

Best Regards,

hi,

it is because my 1+R and 1+B columns are dax measures and not regular column, i actually ahven't thought of using power bi to see if it will work thank you for your recommendation ... but as you can see it won't give you any result for the first and the last row ..so how can i write on a measure than can include them

Hi @Salma_00,

Solution 1: Add the "=" operator.

Column =
CALCULATE (
    PRODUCTX ( Tableau1, [1+R] ),
    FILTER ( ALL ( 'Tableau1' ), 'Tableau1'[Index] >= EARLIER ( Tableau1[Index] ) )
)
    * CALCULATE (
        PRODUCTX ( 'Tableau1', [1+B] ),
        FILTER ( ALL ( 'Tableau1' ), 'Tableau1'[Index] <= EARLIER ( Tableau1[Index] ) )
    )
    * [allocation]

Solution 2:

Column =
VAR temp =
    CALCULATE (
        PRODUCTX ( Tableau1, [1+R] ),
        FILTER ( ALL ( 'Tableau1' ), 'Tableau1'[Index] > EARLIER ( Tableau1[Index] ) )
    )
        * CALCULATE (
            PRODUCTX ( 'Tableau1', [1+B] ),
            FILTER ( ALL ( 'Tableau1' ), 'Tableau1'[Index] < EARLIER ( Tableau1[Index] ) )
        )
        * [allocation]
RETURN
    IF ( ISBLANK ( temp ), 0, temp )

If they are measures, we need the original data to develop a solution or a workaround.

hi Dale,

Sorry to bother you again !!

but i'm kind of lost here wouldn't be the current column involved in the calculation if we ad '=' to the function

i'm  not sure if you understood what i'm trying to do here but just to make stuff a little bit clearer this is what i'm trying to calculate using a dax measure

with at being the allocation column

(1+rt) the 1+R one and (1+bt) the 1+B one

these three columns are already being calculated that's why i can't do a clculated colmun cause they differ form row to row

here is a sample of my inital data with a pivot table... this is what i am currently working on (i use excel 2016 btw)

thank you so much for your help !!
