Remove rows in Power Query based on multiple logical criteria

rowstobedeleted= Table.Sort(Yoursource,{{Quality, Order.Ascending}})

and then you could use Table.Distinct to remove the duplicates.

Hi,

This M code works

let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Informations", type text}, {"Info Quality", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"ID"}, {{"Count", each Table.Min(_,"Info Quality")}}),
    #"Expanded Count" = Table.ExpandRecordColumn(#"Grouped Rows", "Count", {"Informations", "Info Quality"}, {"Informations", "Info Quality"})
in
    #"Expanded Count"

Hope this helps.
