CALCULATE SAMEPERIODLASTYEAR 'DATE'[DATE]

Calculate SamePeriodLastYear 'Date'[Month] ParallelPeriod could work but here the second agrument only takes one parameter and ParallelPeriod requires three

CALCULATE( [Total Sales], SAMEPERIODLASTYEAR('Date'[Date]) )

Tested. CALCULATE , SAMEPERIODLASTYEAR , DATE[DATE] is the right answer

CALCULATE SAMEPERIODLASTYEAR 'DATE'[DATE] Tried and tested 100%

Absolutely, PARALLELPERIOD(<dates>,<number_of_intervals>,<interval>) requires three arguments that are not passed in the proposed code. My vote for: - CALCULATE (by the way, a parenthesis is missed there) - SAMEPERIODLASTYEAR - Date[Date]...here I was initially going for Date[Month] but explanations make me realize it should be Date[Date]

The correct answer is CALCULATE, SAMEPERIODLASTYEAR, 'Date'[Month]

Have tried to build the measures. It woks with the following: 1. SAMEPERIODLASTYEAR(<dates>) Sales Previous Year = CALCULATE([Total Sales],SAMEPERIODLASTYEAR(Date[Date])) 2. PARALLELPERIOD(<dates>,<number_of_intervals>,<interval>) Sales Previous Year = CALCULATE([Total ales],PARALLELPERIOD(Date[Date],-12,MONTH)) 3. DATEADD(<dates>,<number_of_intervals>,<interval>) Sales Previous Year = CALCULATE([Total Sales],DATEADD(Date[Date],-12,MONTH))

CALCULATE is used to change the context in which the data is evaluated. [Total Sales] is your existing measure that calculates total sales. SAMEPERIODLASTYEAR('Date'[Date]) shifts the context of the date by one year, allowing the calculation to be made for the same period last year. This measure will give you the total sales for the same month in the previous year. Make sure that your date table ('Date') is marked as a date table and properly related to your Sales table.

It needs to be 'DATE'[DATE] because SAMEPERIODLASTYEAR only accepts Date columns as arguments. If you try to input the Month column the following error is prompted: "MdxScript(Model) (216, 5) Calculation error in measure •_ProjectMeasures'[Measure Last Year]: A column specified in the call to function 'SAMEPERIODLASTYEAR' is not of type DATE. This is not supported."

AS per Microsoft Definition found in: https://learn.microsoft.com/en-us/dax/sameperiodlastyear-function-dax Example The following sample formula creates a measure that calculates the previous year sales of Reseller sales. DAX: LastYearSales= CALCULATE(SUM(ResellerSales_USD[SalesAmount_USD]), SAMEPERIODLASTYEAR(DateTime[DateKey]))

The data recording frequency is not specified, but based on the snap, we should assume that the data is recorded on a monthly basis. In accordance with this assumption, the syntax using PARALLELPERIOD AND SAMEPERIODLASTYEAR would be: 1. CALCULATE(SUM('Table Name'[Total Sales]), PARALLELPERIOD('Table Name'[Date], -12, Month) 2.CALCULATE(SUM('Table Name'[Total Sales]), SAMEPERIODLASTYEAR('Table Name'[Date])) Given only one argument in the final box, this is the correct answer - CALCULATE, SAMPERIODLASTYEAR, DATE[DATE]

CALCULATE SAMEPERIODLASTYEAR 'DATE'[DATE] / 'DATE'[MONTH]

Answer is wrong and misleading. Correct answers: CALCULATE SAMEPERIODLASTYEAR 'DATE'[DATE] We should use SAMEPERIODLASTYEAR because it as a function would calculate the expression for the previous year period to the period in filter context. Also, we should input the 'DATE'[DATE] column for references the previous year period.

The correct : 1) CALCULATE 2) SAMEPERIODLASTYEAR 3) 'DATE'[DATE] The fonction accepte 3 param like this PARALLELPERIOD(<dates>,<number_of_intervals>,<interval>)

The Suggested Answers are so ridiculous. I answer correctly and later get irritated that again wrong answers under 'Show Suggested Answer'. Mine: CALCULATE SAMEPERIODLASTYEAR 'DATE'[DATE]

Just one question, why there are so many "correct answers" which are actually not correct on this website? Most of the time I need to check the discussions to find the right answer.
