Sum of Value filtering Unique Rows

[Anonymous]

I have a column that I had to split which equated to more rows. I currently use the Distinct Count from the ID row for most count based visuals.

I need to get the sum of certain columns but I dont want it to add every row.

ID	Material Used
1	100
1	100
1	100
2	380
3	421
3	421
4	100

This should only equal 1001. As you can see, the sum of unique values in the materials column wouldnt work since values may match. The ID column needs to be referenced as the control column.

Hello @Anonymous 

I don't know how you want to show it. In my code i take your table, and make a sum of a distincted table and show only the result of that

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTI0MFCK1cHNNgKyjS0gbGMg28TIEINtAlMfCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, #"Material Used" = _t]),
    ChangeType = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Material Used", Int64.Type}}),
    Sum = List.Sum(Table.Distinct(ChangeType)[Material Used])
in
    Sum

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
