Hoping you can assist with this distribution, i'll do my best to explain.
I'd like to distribute cost by month in such a way where it's cumulative(?) on the graph until the cost reaches it's end date, essentially ignoring the start date. When the end date is reached, the cost drops off.
For example, Jan 2018 would have $16,000 in cost (sum of project costs for all projects) and Mar 2021 would have $15,000 in cost (sum of project costs minus project A, since the end date has passed (1/30/2021).
Below is the table and I have a date table as well.
