Dynamic DATESINPERIOD function

[Anonymous]

Hi, I have an SSAS Tabular cube which feeds most of my PBI Desktop Reports.

I am trying to build a measure which compares the selected period in a date filter with the same period prior (in days)

For example, if a user selects 10-June-2020 to 13-June-2020, it will calculate the measure for the 3 days prior (as there are 3 days between the dates)

I have wrote the below DAX however it is just bringing me 0 each time which i know isn't correct - can anyone advise me how to resolve this please?

Many thanks!

TEST2:= CALCULATE('Productivity Advice'[Advice Actions],DATESINPERIOD('Calendar'[CleanDate],dateadd(FIRSTDATE('Calendar'[CleanDate]),-DATEDIFF(FIRSTDATE('Calendar'[CleanDate]),LASTDATE('Calendar'[CleanDate]),day),day), DATEDIFF(FIRSTDATE('Calendar'[CleanDate]),LASTDATE('Calendar'[CleanDate]),day),day))

Hi, my bad sorry - I had a filter applied which was causing the zero

@Anonymous , Can try something like this

Rolling 3 day = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX(Sales[Sales Date]),-3,Day))

Rolling 3 day = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX('Date'[Date]),-3,Day))

Date is my calendar Table

Hi this works fine for a static 3 day period however I want it to be dynamic so if the number of days between the selected dates is 14 for example, it would show the data from the period 14 days.

@Anonymous ,

you can replace it with what-if parameter ?

Rolling 3 day = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX(Sales[Sales Date]),-1* selectedvalues(param[param]),Day))

Rolling 3 day = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX('Date'[Date]),-1* selectedvalues(param[param]),Day))
