DAX Measure to calculate the difference in cumulative within the same column

[Anonymous]

Hello All,

I have the following table with the Cumulative Amounts split across Dates and Type and I want to calculate the amounts in between dates.

For Example: Between 6/27 and 7/25, the amount that was shipped was 35 (721-685) for Type=PF1. Also since 5/30 is the first date in the table, the cumulative amount = Desired Measure

How do I do this in DAX?

I tried using EARLIER but since the dates do not increment by 1 every time, I'm not getting the desired amount

=
VAR CumulativeAmountPreviousDate =
CALCULATE (
SUM ( 'Table'[CumulativeAmount] ),
FILTER (
ALL ( 'Table' ),
'Table'[Date]
= EARLIER ( 'Table'[Date] ) - 1
&& 'Table'[Type] = EARLIER ( 'Table'[Type] )
)
)

RETURN
'Table'[CumulativeAmount] - CumulativeAmountPreviousDate

Hi,

This calculated column formula works

=Data[Cumulative amount]-LOOKUPVALUE(Data[Cumulative amount],Data[Date],CALCULATE(MAX(Data[Date]),FILTER(Data,Data[Type]=EARLIER(Data[Type])&&Data[Date]<EARLIER(Data[Date]))),Data[Type],Data[Type])

Hope this helps.

I tried your solution but I'm getting this error

Calculation error in column '[]: A table of multiple values was supplied where a single value was expected.

Well then you obviously have cases where the same Date and Type combination repeats.  Share a representative dataset and show the expetced result.

You were absolutely right. I grouped them by data and type and your formula worked! Thanks a lot!
