Accummulated total, but start from zero


I have the below table, where the SOH Pre purchase is the running total of SOH start + Manufacture Qty - Units Sold.

However, in some cases, we do not have stock and then have to purchase the quantity to be able to sell to the customer.

At which point our stock on hand is zero.

My problem is in line 3... where we manufacture 9 items. What should the correct formula be for SOH  After Purchase? To take into account purchase stock as well?


Thank you in advance

If I understand your request correctly, you can simply create “SOH After Purchase” column by adding the “Purchase Quantity” column after the cumulative total.


SOH Pre =
    SUM ( Table[Manufacturing Qty ] ),
    FILTER ( Table, [Date] <= EARLIER ( Table[Date] ) )
) - Table[Units Sold ]
SOH after =
    SUM ( Table[Manufacturing Qty ] ),
    FILTER ( Table, [Date] <= EARLIER ( Table[Date] ) )
) - Table[Units Sold ] + Table[Purchase Quantity]

Hi, the problem is that the purchase quantity, is a calculated quantity.

For example if the shortfall in units are 9, such as in line 2, the 9 units must be purchased.

My problem is to add these additional 9 units then back into the running stock on hand quantity.




You are able to add the additional Purchase Quantity back to the running total by simple adding even it is calculated column.

I don't really get what do you mean, can you provide a sample pbix and show us the expected result in the columns.


Hi, I have saved the excel file in this downloadable link.

I appreciate your time.



Hi,  I have calculated the Purchase Qty outside of Power BI for now.
