Calculate difference between two rows in a matrix

[SARAHCH]

Hello,
I want to calculate the difference between the two rows, and display it in the 3rd line, any suggestions please?

While knowing that the value is a sum revenue MTD (month to day), the goal is to display the income of each year according to the months as well as the variation between the month of the current year and the previous year.

Thank you,

Hi @SARAHCH 

Please try this:

First of all, I create a set of sample:

Then add a new table, the value of the table is the field you want to show in the matrix:

Table 2 = {"2022","2023","Variance"}

Then add a measure:

Measure = 
VAR _newValue = SELECTEDVALUE('Table 2'[Value])
RETURN SWITCH(
    _newValue,
    "2022",CALCULATE(SUM('Table'[value]),YEAR('Table'[Date])=2022),
    "2023",CALCULATE(SUM('Table'[value]),YEAR('Table'[Date])=2023),
    "Variance",CALCULATE(SUM('Table'[value]),YEAR('Table'[Date])=2023)-CALCULATE(SUM('Table'[value]),YEAR('Table'[Date])=2022)
)

The result is as follow:

If the above one can't help you, could you please provide more raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution.

Hello @SARAHCH ,

Maybe you could try something like this:

sales amount sum = SUM(FactInternetSales[SalesAmount])

sales amount previous = CALCULATE(SUM(FactInternetSales[SalesAmount]), SAMEPERIODLASTYEAR(DimDate[FullDateAlternateKey]))

sales amount variance = FactInternetSales[sales amount sum] - [sales amount previous]

where you calculate the sum of year, previous and the variance and switch the measures to appear as rows like so:

Let me know if that's what you were looking for.

@SARAHCH 

so you need under 2022, 2023 , a row stating the income, and another row stating the variance ? 

correct ? 

[SARAHCH]

Yes ! I need under 2022 , 2023 a row stating the come, and another row stating the variance. 
this is my exemple :
