Hi there,
I want to unpivot 3 value columns based on the row content given in another column.
Logic: If Category = "Total" unpivot columns Old and New Else unpivot column Value
How to adjust this formula accordingly?
Thank you very much!

Hi Nata,
Do the unpivot as normal, then just add a custom filter.
Paste this into a new blank query to see the steps to take. It's the conditions in the 'filterRows' step that do the work:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("PY0xDsAgCEWv0jC7CIIw9wrdjIN7ky7eP/WbtNPP58GjNbqeOW5KxGq+Qi0QYuqFemp0jnlkAA8DwDyRq3H+OeMeJytzFNtVl+hbEAAuFYJaYr9T+zGM4SrwSCijCy9d7y8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Category = _t, Old = _t, New = _t, Value = _t]),
chgTypes = Table.TransformColumnTypes(Source,{{"Category", type text}, {"Old", Int64.Type}, {"New", Int64.Type}, {"Value", Int64.Type}}),
unpivOthCols = Table.UnpivotOtherColumns(chgTypes, {"Category"}, "Attribute", "Value.1"),
filterRows = Table.SelectRows(unpivOthCols, each if [Category] = "Total" then [Attribute] <> "Value" else [Attribute] = "Value")
in
filterRows
Example query turns this:
