Cumulative Sum for individual material

Hi Neel98 ,

You can achieve this in Power BI. You need to add an [Index] or [Date] column to determine the order of the data.

Here I suggest you to add an Index by material group in Power Query Editor.

Sort your table as you want> Group all rows by Material column > Add index column by M query.

Table.AddIndexColumn([Count],"Index",1)

For reference:

Create Row Number for Each Group in Power BI using Power Query

Calculated column:

Cummulative Sum =
CALCULATE (
    SUM ( 'Table'[Qty] ),
    FILTER (
        ALLEXCEPT ( 'Table', 'Table'[Material] ),
        'Table'[Index] <= EARLIER ( 'Table'[Index] )
    )
)

Result is as below.
