cummulating a value

[Anonymous]

1. Data having Entities for multiple dates(E column), Returns(F column), G column is F col/100 and H col is what we need to get.

2. For minimum date of each entity(here min date is jan 2022), formula should be (J7+100)*(1+G10)-100(j7 is 0, we should take 0 for min value)

3. For other dates, formula should be (H10+100)*(1+G11)-100(H10, need to take previous month value of H col itself)

4. need to derive this H column.
