JShmay,

the solution could be much simpler if you use combination of SUMX function and EARLIER.

Simply add a new calculated column with this formula:

=SUMX (
    FILTER ( Progress, EARLIER ( [ID] ) = [ID] + 1 ),
    Progress[PERCENTAGE]
)

EARLIER returns the current row, so if you compare it with the previous one, it can then return the correct value. This approach might not be very intuitive, but it's much more efficient and could save you lot of time.

The output should then look like this:

Try playing around to achieve the desired result, but I believe this is the simplest and most efficient approach (as far as processing time goes).

Hope this helps.
