I am looking for an M code for a calculated column.
The aim is to search for the value "Yes" in the Type column,

#"Added Custom" = Table.AddColumn(#"Grouped Rows", "Measure", each if List.Contains([All][Type],"Yes") then "Yes" else null),
#"Expanded All" = Table.ExpandTableColumn(#"Added Custom", "All", {"Type"}, {"Type"})
in
#"Expanded All"
