Correct! PARALLELPERIOD needs 3 arguments and it returns the sales for the entire year

There's a Sum missing. CALCULATE(SUM(), SAMEPERIODLASTYEAR(Date[Date]))

Nevermind, Sum isn't necessary as Total Sales is a measure not a column and already calculates the Sum.

This would return the sales on that single date of last year. You need date[month] to get the sales for the entire month of last year.

no. date([month]) will throw an error as the function expects a DATE format and month is integer(or string if format mmm). It MUST be date[Date]

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

SAMEPERIODLASTYEAR accepts a data column, Month will usually be either text (Jan) or Integer (1). so: CALCULATE([Total Sales], SAMEPERIODLASTYEAR('Date'[Date]))

'Date'[Date] is the correct type of data. Then you could make use of Table visualization with a column as 'Date'[Month] to see all the Sales of each previous month

I guess 'Date'[Date]. If you look up for the SAMEPERIODLASTYEAR DAX, it has a Date parameter.

In the middle option, no one isn't absolutely correct. CALCULATE( [Total Sales], SAMEPERIODLASTYEAR ( ENDOFMONTH ( 'Date'[Date] ) ) -- Without EndOfMonth function, you received the total year result instead of the month )

Please delete or ignore my post. The ENDOFMONTH is not needed.

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]

Sorry I was wrong! If you use Date[Month] It will raise an error because The specified month column in the SAMEPERIODLASTYEAR function is not of type DATE. It should be the following configuration: - CALCULATE - SAMEPERIODLASTYEAR - 'Date'[Date]

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]

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.
