## Cumulative total that starts over when the total is negative

I am looking for a way to get the cumulative total to show 0 when it is a negative number and then start cumulating again when the numbers are positive. The following is what I need it to do in the table. It needs to add prior period balance + ON PO + Demand to calculate On Hand (projected) but if the On Hand projected is a -ve number it needs to show 0 and then start accumulating from when the total is +ve. I am trying to create the blue highlighted column below: 1 ACCEPTED SOLUTION  Resolver III

I think this works, maybe, fingers crossed.

All calculated columns - have broken into steps to see what is going on.

``````net =
var AccumPO=CALCULATE(SUM(Table1[PO]),
FILTER(ALL(Table1),Table1[period]<=EARLIER(Table1[period])))
var AccumDemand=CALCULATE(SUM(Table1[Demand]),
FILTER(ALL(Table1),Table1[period]<=EARLIER(Table1[period])))
return AccumPO-AccumDemand+0``````
``````offset = CALCULATE(Min(Table1[net]),
FILTER(ALL(Table1),Table1[period]<=EARLIER(Table1[period])))``````
``SOH(projected) =Table1[net]-[offset]`` 2 REPLIES 2  Resolver III

Thank you this will work. I just need to apply this as a measure since I need to replicate it for multiple products. Thank you so much for your help! @rfigtree
