Aggregated Running total for YoY/Change

[Anonymous]

Hi Everyone,

I have an Install base (customer count) measure which distinctcounts the number of customer IDs as follows:

I also have a similiar measure for the same period last year:

I use the two together to create a measure which reflects the change in customer count:

I'm trying to create the same measure but Aggregated but I'm struggling with this and getting contiguous date selections dax-

Or when i try it this way i get too high numbers:

So to try to recreate what I have on the right end below, summing the months as a running/aggregate total.

Thank you everyone,

Eyal

Hello:

Great. I hope that works for you and if it does can you mark as solution? Thanks...

Hi:

I think you may be gettting that message as you may not have a date table, with continuous dates starting before your data starts and ending at end of ear after. When you mark it as a date table and connect it on the one side to your many-side tables, then the built-in time intel functions work great. 

I can paste some date table DAX code that you can use as a Date Table if you want to.

Dates =

-- Specify a start date and end date

VAR StartDate = Date(2010,1,1)

VAR EndDate = Today()

VAR FiscalMonthEnd = 6

-- Generate a base table of dates

VAR BaseTable = Calendar(StartDate, EndDate)

-- Add the Year for each individual date

VAR Years = ADDCOLUMNS(BaseTable,"Year",YEAR([Date]))

-- Add the calendar month and other month related data for each date

VAR Months = ADDCOLUMNS(

    Years,

    "Month",MONTH([Date]),

    "Year and Month Number",FORMAT([Date],"YYYY-MM"),

    "Year and Month Name",FORMAT([Date],"YYYY-MMM"),

    "Fiscal Year", IF( FiscalMonthEnd = 12, YEAR([Date]), IF( MONTH([DATE]) <= FiscalMonthEnd, YEAR([DATE])-1, YEAR([Date]))),

    "Fiscal Month", IF( FiscalMonthEnd = 12, MONTH([Date]),

        IF( MONTH([Date]) <= FiscalMonthEnd, FiscalMonthEnd + MONTH([Date]), MONTH([Date]) - FiscalMonthEnd))

)

-- Add the Quarter and other quarter related data for each date   

VAR Quarters = ADDCOLUMNS(

    Months,

    "Quarter",ROUNDUP(MONTH([Date])/3,0),

    "Year and Quarter",[Year] & "-Q" & ROUNDUP(MONTH([Date])/3,0))

-- Add the Day and other day related data for each date   

VAR Days = ADDCOLUMNS(

    Quarters,

    "Day",DAY([Date]),

    "Day Name",FORMAT([Date],"DDDD"),

    "Day Of Week",WEEKDAY([Date]),

    "Day Of Year", DATEDIFF (DATE(YEAR([Date]),1,1), [Date], DAY) + 1)

-- Add the Week (assuming each week starts on a Sunday) and other week related data for each date   

VAR Weeks = ADDCOLUMNS(

    Days,

    "Week Of Month (Sunday)",INT((DAY([Date])-1)/7)+1,

    "Week of Year (Sunday)",WEEKNUM([Date],1),

    "Year and Week (Sunday)",[Year] & "-W" & WEEKNUM([Date],1))

-- Add an 'Is Working Day' column which will be true for all days but Saturday and Sunday.

var WorkingDays = ADDCOLUMNS(

    Weeks,

    "Is Working Day", NOT WEEKDAY( [Date] ) IN {1,7})

RETURN WorkingDays

I hope this helps!

Hi @Whitewater100 I tried switiching as follows to my calendar table:

Hi:

When you do your "Same Period LY measure, can you do it like this:

SPLY Install Base LABRA = CALCULATE([Install Base LABRA], SAMEPERIODLASTYEAR(Dates[Date]))

Then subtract your initial measure from this. I'll call it VAR Install Base LABRA

To get cumlative total for the VAR Install Base LABRA

= CALCULATE([VAR Install Base LABRA], FILTER(ALLSELECTED(Dates), 
 Dates[Date] <= MAX(Dates[Date])))

Normally this should work. Can you give it a try? Thanks
