Help me divide shipping volume evenly using cumulative sum...

[DistributionExceller]

Here's my situation: I have a cumulative sum function in place that shows volume that I expect along a shipping dock at my distribution facility. I need a formula that re-starts the cumulative sum function if I enter a team number or some other indicator in an adjacent cell.

In the below sample, the first column with lots of data shows cumulative total volume. The second column shows volume per door. The third column shows the shipping door numbers. To the right, our supervisors will input the # of teams that are available that day and a formula determines the volume that each team should have to equally divide the work, in this case 15,956.

I want to be able to scan down the cumulative volumn column and place a "1" to indicate the ending door for team 1 at the door that has the cumulative volume that most closely resembles the optimum volume per team (15,956). At this point, I want the cumulative sum formula to reset so that I can quickly identify the door range for team 2 by looking again for a volume that is near 15,956, and so on.

Please help me finish this project!!!

I can't figure out your columns of data. My proposal is to use a helper column:

	A	B	C
1	Input	Helper	Change Docks
2	5000	=A2
3	6500	=IF(B2+A3>3500,A3,B2+A3)	=IF(B3<>B2+A3,"1","")

Drag down the formulae from B3 and C3 to the length of your table. Whenever you see a 1 in column C, then you need to change doors.
