Comparing between two years based on selected branch

[MAbouelatta]

Hello Friends

I would like to compare between two years (12 months) based on the selected branch from slicer, 

The comparing goes in right way only when not selecting any branch from slicer and it compares the sum of all branches, but after selecting any branch it gives me the below error.

I have a table for Calendar and I did the releationship between it and my main table.

and I'm using this measure for last year as follows "

Total LP Act. Spend =

CALCULATE([Total Act. Spend], SAMEPERIODLASTYEAR('Calendar'[Date]))"

I hope if anyone can solve it

Hi @MAbouelatta ,

Here's the simple example data I created:

Date	Value
2023-01-01	100
2023-02-01	100
2023-03-01	100
2023-04-01	100
2023-05-01	100
2023-06-01	100
2024-01-01	50
2024-02-01	50
2024-03-01	50
2024-04-01	50
2024-05-01	50
2024-06-01	50

Create a date table and create a join between the two tables:

Date = CALENDAR(MIN('Table'[Date]),MAX('Table'[Date]))

Create a MEASURE to calculate the sum of the current year:

CurValue = CALCULATE(SUM('Table'[Value]),FILTER('Table',YEAR('Table'[Date])) = YEAR(TODAY())))

Create a MEASURE to calculate last year's total:

PreviousValue = CALCULATE(SUM('Table'[Value]), SAMEPERIODLASTYEAR('Date'[Date]))

You can calculate whether the number of rows of last year's data selected in your data table is correct by using the following measure:

Last Year Count = 
CALCULATE(
    COUNTROWS('Table'),
    SAMEPERIODLASTYEAR('Table'[Date])
)

Using a multi-row card visual object instead of showing two years of data comparison in a table, dragging a MEASURE into a table will report an error.
