Filter rows by last update in Query Editor

[JoaoMS]

Dear, I have the following table where an invoice can have many "Register Numbers":

Register_Number	Invoice	Value	DateHour
14500	E001-00605	1000	8/02/2020 10:00
14600	E001-00605	-1000	8/02/2020 16:00
14700	E001-00605	1000	8/02/2020 16:10

What I want to filter from Query Editor is just the last version of the Registered Invoice based either on the "DateHour" column or the "Register_Number" column.

The output table should be:

Register_Number	Invoice	Value	DateHour
14700	E001-00605	1000	8/02/2020 16:10

I don't want to use DAX because I'd have to create a new table.

Regards

Joao

Hi @JoaoMS ,

You can try this code:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQxNTBQ0lFyNTAw1DUwMDMwBXIMDcBiFvoGRvpGBkYGCoYGVkCRWB2QejNM9bqYGswQGsyJscDMyhCoPhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Register_Number = _t, Invoice = _t, Value = _t, DateHour = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Register_Number", Int64.Type}, {"Invoice", type text}, {"Value", Int64.Type}, {"DateHour", type datetime}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each List.Max(#"Changed Type"[DateHour])),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "Max_Value", each if [DateHour] = [Custom] then 1 else 0),
#"Filtered Rows" = Table.SelectRows(#"Added Custom1", each ([Max_Value] = 1))
in
#"Filtered Rows"

Hi @JoaoMS ,

Using a M query as below:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQxNTBQ0lFyNTAw1DUwMDMwBXIMDcBiFvoGRvpGBkYGCoYGVkCRWB2QejNM9bqYGswQGsyJscDMyhCoPhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Register_Number = _t, Invoice = _t, Value = _t, DateHour = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Register_Number", Int64.Type}, {"Invoice", type text}, {"Value", Int64.Type}, {"DateHour", type datetime}}),
#"New step" = Table.RemoveColumns(Table.SelectRows(Table.AddColumn(Table.AddColumn(#"Changed Type", "Custom", each List.Max(#"Changed Type"[DateHour])), "Max_Value", each if [DateHour] = [Custom] then 1 else 0), each ([Max_Value] = 1)),{"Custom", "Max_Value"})
in
#"New step"

Finally you will see:

Best Regards,
Kelly
