Nested Calculation item not working

[han_rj]

I have created a calculation item for This Year and Prior Year and wanted to calculate Variance for it.

But the varaince calculation item is not working 

Variance = CALCULATE(SELECTEDMEASURE(),Time_Period[Time_Period_Grp] = "TY") -  CALCULATE(SELECTEDMEASURE(),Time_Period[Time_Period_Grp] = "LY")

A calculation group is only called once per measure, so you cannot nest them like this. You would either need to have the variance in a separate calculation group or replicate the time intelligence logic in the TY & LY calculation items.

Thank You for responding, I tried both ways did'nt work

Try

Variance =
VAR ThisYear =
    CALCULATE ( SELECTEDMEASURE (), DATESYTD ( 'Date'[Date] ) )
VAR LastYear =
    CALCULATE (
        SELECTEDMEASURE (),
        DATEADD ( DATESYTD ( 'Date'[Date] ), -1, YEAR )
    )
VAR Result = ThisYear - LastYear
RETURN
    Result

Hi @han_rj 

Could you please provide some 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. You can refer the following links to share the required info:

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

@v-zhengdxu-msft , Thank You for responding

This is the sample data

Calculation Items used

Last_Year = CALCULATE(SELECTEDMEASURE(),'Table'[Last_Year_Ind] = "Y")

This_Year = CALCULATE(SELECTEDMEASURE(),'Table'[This_Year_Ind] = "Y")

YOY = CALCULATE(SELECTEDMEASURE(),'Table'[This_Year_Ind] = "Y") -

CALCULATE(SELECTEDMEASURE(),'Table'[Last_Year_Ind] = "Y")

Current Results

Expected

I want variance for the current year only

Hi @han_rj 

Please try this:

First of all, Create a measure:

Measure = SUM('Table'[Sales])

Then add a calculation group:

Last_Year = CALCULATE(SELECTEDMEASURE(),'Table'[Last_Year_Ind] = "Y")

This_Year = CALCULATE(SELECTEDMEASURE(),'Table'[This_Year_Ind] = "Y")

YOY =
CALCULATE ( SELECTEDMEASURE (), 'Table'[This_Year_Ind] = "Y" )
    - CALCULATE ( SELECTEDMEASURE (), 'Table'[Last_Year_Ind] = "Y" )

Finally, create a Matrix and the result is as follow:

Thank You @v-zhengdxu-msft for responding the format I am looking for is like this

CY, TY label and the Year.

If we exclude the Year in the column we get the correct results but when we add Year to the column the variance is off like this
