How to filter off 'duplicate' records

[gancw1]

I have a table of quiz submissions as show below and I need to discard the student records with Incomplete status (#5) if there is already a record with Submitted status (#4)

How can I do this in Power Query ?

Hello ! 

you need create in Power Query table with name "Result_Table" and List with name "Submited_list"
code for its items bellow.

table with name "Base_Table" - it is your table from topic start

Submited_list

let
    Source = Base_Table,
    #"Filtered Rows" = Table.SelectRows(Source, each ([Status] = "Submited")),
    Custom1 = #"Filtered Rows"[Name]
in
    Custom1

 
Result_Table

let
    Source = Base_Table,
    #"Added Custom1" = Table.AddColumn(Source, "Completed_List", each List.Contains(Submited_list, [Name])),
    #"Added Conditional Column" = Table.AddColumn(#"Added Custom1", "check", each if [Completed_List] = true and [Status]<>"Submited" then 0 else 1),
    #"Filtered Rows" = Table.SelectRows(#"Added Conditional Column", each ([check] = 1)),
    #"Removed Other Columns" = Table.SelectColumns(#"Filtered Rows",{"SN", "Name", "Status"})
in
    #"Removed Other Columns"

I hope it will help you 🙂

Best Regards !

@SolomonovAnton ,

Thanks for the solution.  The List.Contains( ) is the look up function that I was looking for !
