Sum of previous values (no date column)

Hi Community,

 

I am working on the sample below , the objective is to calculatd in new column the Sum of Amounts where ID < Current_ID, in the right side the result I am supposed to get:

 

Data.png

Here is my Dax measure but it returns an empty column

Measure =

Var currentID=SUM('Table'[ID])

Return

SUMX(FILTER('Table','Table'[ID]<currentID),'Table'[Amount])

 

Thank you in advance

Hello @Greg_Deckler

I confirm that the updated DAX returns the value taking into account only key1 while key 2 is excluded.

Once I expanded the Key2 data I got incorrect values:

Data 5.png

So I tried to add key2 to the extent, even though I didn't get the right values

Measures 
VAR currentID-MAX('DATA'[ID])
VAR key1 to MAX('DATA'[Key 1])
VAR Key2 MAX(DATA[Clave 2])
Return
SUMX(FILTER(ALL('DATA'),'DATA'[Key 1]-key1 && 'DATA'[Key 2]-Key2 &&'DATA'[ID]<currentID),'DATA'[Amount])

Thank you in advance

@DataVitalizer , new column

SUMX(FILTER('Table','Table'[ID]< earlier('Table'[ID])),'Table'[Amount])

 

new Measure

SUMX(FILTER(all('Table'),'Table'[ID]< max('Table'[ID])),'Table'[Amount])

Hi,

Thank you @Greg_Deckler , @amitchandak  for your quick reply.

I've tried both suggested measures, here below what I got:

The returned values are different than the target, here i tried to clarify more the need:

Thank you in advance.

@DataVitalizer - I updated my post after I originally posted, please check again, I took Key1 into account.

Hi @DataVitalizer ,

 

We can create a measure to meet your requirement.

 

Measure = 
CALCULATE(SUM('Table'[Amount]),FILTER(ALLSELECTED('Table'),'Table'[Key 1]=MAX('Table'[Key 1]) && 'Table'[ID]<MAX('Table'[ID])))

If it doesn’t meet your requirement, could you please show the exact expected result based on the table that you have shared?
