Adding rows in power Pivot for Excel -datamodel

[nikhil0511]

Hello Forum,

I need an assistance in adding up two or multiple values for my calculation in datamodel. Please find the below sample data and output I expect.

Parent	Child	Info
A	1	22
A	2	45

now I want to sum the info values as per the Parent and remove the duplicate parent values. so that I get unique values at the end.

Please note I am doing this in Data model -PowerPivot for Excel.

Hi @nikhil0511 ,

Is this your expected result?

If so, I can do it in Power Query. Please copy-paste the below code in a blank query to see the details.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTIEYiMjpVgdCNcIiE1MlWJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Parent = _t, Child = _t, Info = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Parent", type text}, {"Child", Int64.Type}, {"Info", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Parent"}, {{"Child", each null, type nullable number},{"Info", each List.Sum([Info]), type nullable number} }),
    #"Appended Query" = Table.Combine({#"Changed Type", #"Grouped Rows"})
in
    #"Appended Query"

I also attach my sample below for your reference.

Hello @v-yanjiang-msft,

Thanks for the response. 

I was able to perform the following output in Power Query using GroupBy and Sum. but i was expecting this to be done in Excel Data Model, as the Info column I provided in example is a calculated column in DataModel and needs to provide me the result in DataModel.

Regards
