Distributing values between start and end dates and get the cumulative

[MAbdelRazik]

I am trying to distribute values between dates. I have a start and finish date and a certain value that I want distributed between these 2 dates. For example

Task	Start	End	Value
A	1/1/2020	1/10/2020	1000
B	1/11/2020	1/20/2020	1000
C	1/21/2020	1/30/2020	1000

I need the outcome to be like this:

Date	Value	Cumulative value
1/1/2020	100	100
1/2/2020	100	200
1/3/2020	100	300
1/4/2020	100	400
1/5/2020	100	500
1/6/2020	100	600
1/7/2020	100	700
etc....	100....	800...

So far, I created a date table and was able to use a measure to calulcate the value for each date but I am struggling with the cumulative part. Here's the measure I used for the values distribution over time:

Value = CALCULATE(

sum (Data[values]),

FILTER(

Data,

Data[StartDate]<=max( 'DateTable'[Date])

&& Data[EndDate] >= max ('DateTable'[Date])))

Any help with this will be greatly appreciated.

Hi  @MAbdelRazik ,

Create a table as below:

Table 2 = CALENDAR(MIN('Table'[Start]),MAX('Table'[End]))

Then create 2 measures as below :

_Value = 
var _table=ADDCOLUMNS('Table 2',"value",CALCULATE(MAX('Table'[Column]),FILTER(ALL('Table'),'Table'[Start]<='Table 2'[Date]&&'Table'[End]>='Table 2'[Date])))
Return
MAXX(_table,[value])

_Cumulative value = SUMX(FILTER(ALL('Table 2'),'Table 2'[Date]<=MAX('Table 2'[Date])),'Table 2'[_Value])

And you will see:

@MAbdelRazik , check I have done a split in new table here.

Post that you can run cumulative

[MAbdelRazik]

@amitchandak I have reached a similar outcome to what you have there. I am looking for a next step to have cumulative values. So, in November, the values will be your Oct and Nov added together and so on.

@MAbdelRazik So did you create a table for breaking things out or a measure? If a table, create a calculated column. If a measure, do measure aggregation and add a column using ADDCOLUMNS then filter down to the current in context date. The column calculation goes something like:

Column = SUMX(FILTER('Table',[Date]<=EARLIER([Date]),[Value])

Did you use something like Open Tickets to break things out?

@Greg_Deckler So, I had the one table with StartDate, EndDate and valuePerDay. I will call this Data_table. 

I created a table that has dates and I will call this DateSTable. I created a measure using this code:

ValuePerDay = CALCULATE(

sum (Data_Table[valuePerDay]),

FILTER(

Data_Table,

Data_Table[StartDate]<=max( 'DateSTable'[Date])

&& Data_Table[EndDate] >= max ('DateSTable'[Date])))

Now I have a visual which has all the dates from the DateSTable and the measured values. I am trying now to get the cumulative values.

I am not sure where to add the column suggested in your method below. I also can't seem to refer to the measure in a calculated column. I am sure I am doing something wrong but I am not sure what it is.

@MAbdelRazik OK, if that is your measure, we will go the measure route. So:

Cumulative Measure =
  VAR __Date = MAX('DateSTable'[Date])
  VAR __Table = FILTER(ALL('DateSTable'[Date]),[Date]<=__Date)
  VAR __Table1 = 
   ADDCOLUMNS(
      __Table,
      "PerDay",SUMX(FILTER(Data_Table,Date_Table[StartDate]<=[Date]&& Data_Table[EndDate] >=[Date])
   )
   VAR __Table2 =
     ADDCOLUMNS(
       __Table1,
       "Cumulative",SUMX(FILTER(__Table1,[Date]<=EARLIER([Date])),[PerDay])
     )
RETURN
  MAXX(FILTER(__Table2,[Date]=__Date),[Cumulative)
