Cumulative sum in column until it finds the certain value

[Kopec]

Hi,

I need to write this to the Explicit measure in the Power Pivot:

Start with cumulative sum in column (One by one; It can be ascending or descending.), when it hits the first 0 in the cell, stop the calculation and show the sum from 1 row to the row where is the 0 placed.

Can anybody help with the measure?

I have only 0 or 1 in the Column. When it is needed I can replace 0 for „Null“ or some text.

Thank you,

Jan

Ps: I additionally added the picture and sample data.

Hi, @Kopec 

According to your description and sample pictures, I can clearly understand your requirement, I think you can try to create a calculated column like this to achieve your requirement:

Result =

CALCULATE(SUM('Tabulka1'[Data]),FILTER(ALL(Tabulka1),[Date]>=EARLIER(Tabulka1[Date])&&[Name]=EARLIER(Tabulka1[Name])))

And you can get what you want, like this:

@Kopec Do you have any column that defines "before" like an Index column, etc.

Sorry, having trouble following, can you post sample data as text and expected output?
