Would you be able to share a sample where you are trying to do this? or may be share your Excel file with the raw data and the expected output you want to see

KEY is main dimension

Month is time dimension

logic is:

1.for each KEY, if Month is past month then wanted result is 0

2.for each KEY, if Month is equal or larger than current month, then depending on Balance value (<0 or >=0) to use different calculation way (details in attached file)

most hard part to me is using cumulative value of above rows as a input for next row, in excel it's easy.
