Calculate sum on higher level - unexpected result

[Tido]

Hi,

maybe you can help me by solving the following issue. I want calculate the total sum of some products. If the total sum for each product is lower than zero, it shall get the value zero. On product level this works properly with the formula below, but not on higher aggregated level.

Product	Stock	Dispatch	Total	Reality
A	1000	-800	200	200
B	0	-100	-100	0
C	200	-100	100	100
D	200	-300	-100	0
			100	100

Instead of the red marked 100 pcs, I expect a value of 300 pcs.

Currently I use the following formula / measure, to calculate the value along the time:

CumStockQty =
VAR Reality = CALCULATE(StockData_Stock[Stock Qty] - StockData_Dispatch[Total Dispatch Qty1];
                   FILTER(all(StockData_Date); [Date] >= max(StockData_Date[Date]) - 365 && [Date] <= max(StockData_Date[Date])))

VAR z = if(Total>0;Total;0)
Return z

Any idea what I can adjust to get a figure of 300 pcs on the highest aggregation level?

Thanks for your support!!

Hi Greg,

thx for your response. I've tried to adjust the measure according to your proposal:

CumStockQty_real =
VAR single = CALCULATE(StockData_MasterData[Stock Qty] + StockData_Receipt[Total Receipt Qty] + StockData_Dispatch[Total Dispatch Qty1];
             FILTER(all(StockData_Date); [Date] >= max(StockData_Date[Date]) - 365 && [Date] <= max(StockData_Date[Date])))

VAR total = SUMMARIZE(StockData_Date;StockData_Date[Date];"Qty";if(single > 0; single;0))

RETURN if(HASONEVALUE(StockData_MasterData[ItemNumber]);if(single > 0; single;0);SUMX(total;[Qty]))

But at the end, I get out the same result:

Do you have an idea, what I'm doing wrong?

Thx

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376
