Hi, I need to have the the latest date and the corresponding Fee of a Customer table having many different customers and many rows for the same Customer. This can be done easily in SQL Server with ROW_NUMBER and then ordering It by the Latest Date.
Input:
Customer | Date | Fee |
A | 13/01/2020 | 10 |
A | 25/01/2020 | 15 |
B | 26/01/2020 | 12 |
B | 16/01/2020 | 7 |
B | 17/01/2020 | 13 |
C | 05/01/2020 | 20 |
C | 02/01/2020 | 25 |
C | 20/02/2020 | 15 |
Temporal
Customer | Date | Fee | Row Number |
A | 13/01/2020 | 10 | 2 |
A | 25/01/2020 | 15 | 1 |
B | 26/01/2020 | 12 | 1 |
B | 16/01/2020 | 7 | 3 |
B | 17/01/2020 | 13 | 2 |
C | 05/01/2020 | 20 | 2 |
C | 02/01/2020 | 25 | 3 |
C | 20/02/2020 | 15 | 1 |
Output:
Customer | Date | Fee |
A | 25/01/2020 | 15 |
B | 26/01/2020 | 12 |
C | 20/02/2020 | 15 |

Hi, @Ricardofaster , it's as easy as in SQL to process in PQ given there's in PQ an equivalent of Grougp By clause in SQL.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Tc7BDcAgDAPAXfJGwjFKebcdA7H/GgUqgX/xJbLSmt2WzEuGZ4KYAdbT7wz1WP5Mv9S53dXr4arnZfk7Rmg9cZzqsZ3IYyXv9A8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Customer = _t, Date = _t, Fee = _t]),
#"Changed Type" = Table.TransformColumns(Source,{{"Date", each Date.FromText(_, "fr")}, {"Fee", Number.From}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"Customer"}, {{"temporal", each Table.Sort(_, {"Date", Order.Descending}){0}}}),
#"Expanded temporal" = Table.ExpandRecordColumn(#"Grouped Rows", "temporal", {"Date", "Fee"}, {"Latest Date", "Fee"})
in
#"Expanded temporal"
Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension! |
DAX is simple, but NOT EASY! |
Hi @CNENFRNL ,
Thanks for your response but with your solution I will only get the sum of the Fees by Employee. What I need is the unic value of the Fee corresponding with the latest date by Customer.
Hi, @Ricardofaster , I've amended the code in line with your requirement. Pls try it again.
