Hi,
I'm trying to create a new column [New Qty] using DAX which convert the [Diff Qty] to the max values of [Usage Qty] in the same row and extend the [New Qty] to the next row until the sum equals the [Diff Qty], based on Product ID. Could anyone help me on that? Thanks.

Hi, @Troyes
You can click ‘Edit Queries’ to enter into the Query Editor, go to ‘Add Column’ -> click ‘Index Column’ to add index column (start from 0).

Then, you can create a calculated column as follows:
New QTY =
VAR t =
FILTER (
'Table',
[Product] = EARLIER ( 'Table'[Product] )
&& [Index] < EARLIER ( 'Table'[Index] )
)
VAR totalDiff =
CALCULATE ( SUM ( 'Table'[DIFF QTY] ), t )+[DIFF QTY]
VAR minleft =
CALCULATE ( SUM ( 'Table'[Usage QTY] ), t )
RETURN
IF (
minleft > totalDiff,
0,
IF (
[DIFF QTY] <> 0,
[Usage QTY],
IF (
minleft = 0,
0,
IF ( minleft + [Usage QTY] > totalDiff, totalDiff - minleft, [Usage QTY] )
)
)
)
Result:
