Help with Identifying Correct Function to Use

[RAW_PhD]

I have a table with 3 columns:

Person Name, Test ID #, and Pass/Fail

I need to identify which row has a person who has failed a specific Test ID# total of 3 times.

I've tried sorting on the Test ID#, and counting the people column, but that doesn't tell me if they passed/failed.

I can't seem to come up with the logical expression to identify who failed which test 3 times.  

Any help would be greatly appreciated!

Hi @RAW_PhD ,

Consider grouping by [Test ID #] and [Person Name] and counting the number of fails:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcnRU0lEyNDAwBFJuiZk5SrE60UpOTlgEnZ0RggGJxcVgQRcXLIKurlgECVoEVwmzyAibRUbI2mEWGRFtkRE2i4yJtsgYLhgLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Person Name" = _t, #"Test ID #" = _t, #"Pass/Fail" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Person Name", type text}, {"Test ID #", Int64.Type}, {"Pass/Fail", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type",{"Person Name", "Test ID #"},{{"Data", each _}, {"Number of fails", each Table.RowCount(Table.SelectRows(_,(x)=> x[#"Pass/Fail"]="Fail"))}}),
    #"Expanded Data" = Table.ExpandTableColumn(#"Grouped Rows", "Data", {"Pass/Fail"}, {"Pass/Fail"})
in
    #"Expanded Data"

For specific ids, next you can filter further.
