Add column to a matrix with % of increase vs previous week

[pasno]

Hello guys,

I'm working with a matrix, and I conted the number of whipment splitted by Area (rows) and year-month (columns).

I'd like to add one more column, but I fond some issues when I try to create the new measure.

My idea is to create a column that shows the % of variation in comparison with the last n months (let's say 2 month).

So, for example, the measure for March for the 2° row will make this calculation:

Average(13:16) [average of 2° row monhts January and February]

/

24 [value of 2° row for March]

Do you have any idea to help me?

Thank you very much!!

Hi @pasno ，

1.Create a calendar table.

Calendar =
ADDCOLUMNS (
   CALENDAR ( MIN ( 'Table'[Date] ), MAX ( 'Table'[Date] ) ),
    "YearMonth",
        YEAR ( [Date] ) & "-"
            & MONTH ( [Date] )
)

2.Create a What-if parameter and put it into a slicer.

3.Create this measure.

Percentage = 
DIVIDE (
    DIVIDE (
        CALCULATE (
            SUM ( 'Table'[Value] ),
            DATESINPERIOD ( 'Calendar'[Date], LASTDATE ( 'Table'[Date] ), -3, MONTH )
        )
            - SUM ( 'Table'[Value] ),
        [Parameter Value]
    ),
    SUM ( 'Table'[Value] )
)
