Helper IList Sum except specific value
I have a table that looks something like this:
| Category | Location 1 | Location 2 |
| Cat 1 | 5175.6 | 1725.2 |
| Cat 2 | 9004.6 | 3001.533 |
| Cat 3 | 3178.6 | 1059.533 |
| Cat 4 | 5685 | 1895 |
| Cat 5 | 7400.8 | 2466.933 |
| Cat 6 | 1008.8 | 336.2667 |
| Cat 7 | 708.8 | 236.2667 |
| Cat 8 | 16868.2 | 5622.733 |
| Cat 9 | 8442 | 2814 |
| Cat 10 | 8402 | 2800.667 |
I want to create a column that sums Location 1 by all values except Category 8. I don't want to filter out Category 8 as I'll need those values for the calculations of another column.
I tried nesting a table.selectrows within a List.Sum, but that didn't give me what I need.
List.Sum(Table.SelectRows(#"Added Custom", each not ([Category] = "Cat8")))
Your basic idea is correct. The below works:
List.Sum(Table.SelectRows(#"Changed Type", each [Category] <> "Cat 8")[Location 1])You need to include the field you want to sum at the end. Appending [Location 1] tells it what column of the filtered table to sum.
Full code:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("XY8xDsIwDEWvUmWuLNtJbGdm5QZVhwohxEIl1IXbE6coFDbnvfzvZJrCadmut/X5CmM4r5dlu6+PgY4HHsI8tnuNZ9IMUgdSzsDdcUUFMTUXEQlyjN1Gh6S2JzGXH5u8Vyy7s5I7d6AJEawOnESgHFJ7FVqzMQqwiHarnv1I/pcOSUwMuK1mBj00lwotJXdslL7/xyZwF/VdrXN+Aw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"(blank)" = _t, #"(blank).1" = _t, #"(blank).2" = _t]), #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]), #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Location 1", Currency.Type}, {"Location 2 ", Currency.Type}}), #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each List.Sum(Table.SelectRows(#"Changed Type", each [Category] <> "Cat 8")[Location 1])) in #"Added Custom"How to use M code provided in a blank query:
1) In Power Query, select New Source, then Blank Query
2) On the Home ribbon, select "Advanced Editor" button
3) Remove everything you see, then paste the M code I've given you in that box.
4) Press Done
5) See this article if you need help using this M code in your model.
