How to add previous row value with current one and then keep getting the summation

[Anonymous]

HI below is the table as input in power bi and below that is the output i would require in power bi. Please let me know how is it possible in calculated column or Measure. its basically addition of previous row with current row please see the example below:

Input:

Date                       Value
22march 2017             3

23march 2017             3

24march 2017             2

25march 2017             11

01 January 2018           5

Output:

Date                       Value      Final Value
22march 2017             3               3

23march 2017             3               6

24march 2017             2               8

25march 2017             11            19

01 January 2018           5             24

I would require the Final value to be calculated. Please let me know the steps or formulae required.

thanks,

How do we calculate the prior row value and current row value? For example the Final Value being 3, 6, 5, 13

Date                       Value      Final Value
22march 2017             3               3

23march 2017             3               6

24march 2017             2               5

25march 2017             11            13

01 January 2018           5             16

Hi,

Try this calculated column formula

=[Value]+lookupvalue(data[value],data[date],calculate(max(data[date]),filter(data,data[date]<earlier(data[date]))))

Hope this helps.

Hi @Anonymous,

You can create a calculated column: 

Column = CALCULATE(SUM('Table3'[Value]),FILTER('Table3','Table3'[Date]<=EARLIER('Table3'[Date])))

Hello!! This is pretty much what I need but based on columns like in the picture below. Can I add a measure to add columns 2 into column 1, column 3 into colunm 2....

Thank again for the help.

Hi,

Is it possible to do this for each week? I mean summing the values per week.

Thanks.

@v-qiuyu-msft thanks for the solution, it was exactly what I was looking for. I just have another question. Is it possible to perform the same calculation using a measure? If not, not a problem.

[v-qiuyu-msft]

Hi @handrade,

Of course. You can create a measure below: 

Measure=CALCULATE(SUM('Table3'[Value]),FILTER(all('Table3'),'Table3'[Date]<=Max('Table3'[Date])))

Hi @v-qiuyu-msft ,

your formulas really helped me a lot. Now I have the question if the same calculation can be made in Power Query (Custom column)?

Link to image . Cuz I want to use my calculated columns in Data pane (Link to image ) as an import into new Power Queries.

Thanks a lot in advance.

Best regards
