Create a calculated column like running total but have limitations

Hi guys,

I have a problem. I want to create a calculated column call ExpectedOutcome .

The value of column ExpectedOutcome for 1st row where No.Session = 1 is calculated by Score + 90.
From the second row, the value of ExpectedOutcome = previous ExpectedOutcome + Score.

The value of ExpectedOutcome is always in the range of 0 - 100. If it < 0, then we put 0 as the value. If it > 100, then we put 100 as the value.

It seems like calculate a running total, but it is not. And I do not know how to solve this problem.

Plz help me. Thank you.Screenshot_10.png

Hi  @Phuonghm22 ,

There is no recursive function in computed columns, you can use Power Query:

Here are the steps you can follow:

1. Power Query – Home  -- Advanced Editor.

2. Put the following code in it.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Tc/RDcAgCEXRXfjWxIfV2lmM+69REAv9MYeGeO2cBErEtNKU81N1Xa7m6q7bNUS5bT7+EUVYjYgFRAhRQqTQfstRQ+QwgtrLvdgvaDHXM+wmn4H3YNaqXc9aPRtalSev9QI=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [No.Session = _t, Score = _t]),
    test = Table.TransformColumnTypes(Source,{{"No.Session", Int64.Type}, {"Score", Int64.Type}}),
    #"Added Custom" = Table.TransformColumns(Table.AddColumn(test, "Custom", (x)=>  List.Accumulate(List.Range(test[Score],0,x[No.Session]),0,(x,y)=>if x+y >=10 then 10 else if x+y<=-90 then -90 else x+y)             ),{"Custom",(x)=>x+90})
in
    #"Added Custom"

3. Result:

Thank you for reply. But I have another problem that make thing more complicated. The same data sample as I already provided before, but now it have a column that have multiple ID, and I have to use that column ID to group by while calculating. How can I do to handle this problem?
