Need help formatting data structure.

[Anonymous]

Hi so I have a data source that gives a sales persons numbers in this format:

Date	Sale amount
4/1/20	$100
6/1/20	$200
6/3/20	$200

I need to be able to format the data so it becomes a cumulative total and includes all the months up to the current month.

Date	Sales Amount (Cumulative Total)
4/1/20	$100
5/1/20	$100
6/1/20	$500
7/1/20	$500
8/1/20	$500

Any ideas on how to create a data table that has this structure?

Thanks as always!!

@Anonymous , you have to create measure like, with a date table

Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(date,date[date] <=maxx(date,date[date])))
Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(date,date[date] <=max(Sales[Date])))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

Hi @Anonymous 

first create a calendar table

Calendar = CALENDARAUTO()

then you can create whether a calculated column

Sales Amount (Cumulative Total) =
CALCULATE(SUM(Table[Sale amount]), FILTER(ALL(Table]), Table[Date] <= EARLIER(Calendar[Date])))

or measure 

Sales Amount (Cumulative Total) =
CALCULATE(SUM(Table[Sale amount]), FILTER(ALL(Table]), Table[Date] <= MAX(Calendar[Date])))

 for this calendar table

This is very close with the measure but it is giving an unexpected result. It is assigning the total sum of that column to a every person. Not a cumulative total of each person for each month.

do you have relationships between calendar table and sales table?

what table (calendar or sales) do you use as date columns in visual?
