DAX help
Hi,
I have data as mentioned below and wanted to create New Val calculated column, whenever there is negative make it zero and next row record should be substracted negative values.
In the below example, 1/1/2025 role 2 has -25 and it has to be zero in New Val and next row that is role 3 val has 40, but New Val should 40-25 i.e 15 should get it.
Not sure how to create calculated column to get values as I described.
Any help.
Thanks,
Thimma

Hello Anonymous ,
I can suggest quickly with the help of creating INDEX in Power Query.DAX for the new column will be like below:
New Value = VAR PV = LOOKUPVALUE('Table'[Val],'Table'[Index],'Table'[Index]-1) RETURN IF('Table'[Val]<0,0, IF('Table'[Index] =1,'Table'[Val], IF('Table'[Val]>0 && PV < 0, 'Table'[Val] + PV , 'Table'[Val])))Output looks as below:
Attached pbix as well for your refrence.

No, that not right. You can create index without which how you know the order of the value column?
So, you have to figure out a way of creating index for your data. Atleast ROW NUMBER should be created.
Anonymous , Try using below dax for calculated column
New Val =
VAR CurrentVal = 'Table'[Val]
VAR PreviousRow =
CALCULATE(
SUM('Table'[Val]),
FILTER(
'Table',
'Table'[Dt] = EARLIER('Table'[Dt]) &&
'Table'[role] = EARLIER('Table'[role]) - 1
)
)
VAR Adjustment =
IF(PreviousRow < 0, -PreviousRow, 0)
RETURN
IF(CurrentVal < 0, 0, CurrentVal - Adjustment)Hi Anonymous
