[Power Query] Get max value of rows with grouping.
I am trying to group data set to reflect the Max of the Total column.
I have this data set
| Date | ProductID | Price | Orders | Total |
| 1-Jan | a12 | 11 | 1 | 11 |
| 1-Jan | a13 | 12 | 3 | 36 |
| 1-Jan | a13 | 12 | 2 | 24 |
| 2-Jan | a12 | 11 | 4 | 44 |
| 2-Jan | a12 | 11 | 2 | 22 |
| 2-Jan | a12 | 11 | 5 | 55 |
I want to get it grouped by Date and ProductID and reflect Max on this date for ProductID
| Date | ProductID | Price | Orders | Total | Max |
| 1-Jan | a12 | 11 | 1 | 11 | 11 |
| 1-Jan | a13 | 12 | 3 | 36 | 36 |
| 2-Jan | a12 | 11 | 5 | 55 | 55 |
Hi Beck ,
You can use the group by feature:
Here's a sample code
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtT1SsxT0lFKNDQCkoaGIALCiNVBljUGCYKUgBjGZrhkwdgELGuEabIJCOOUBes1wiVrCsKmSrGxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, ProductID = _t, Price = _t, Orders = _t, Total = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"ProductID", type text}, {"Price", Int64.Type}, {"Orders", Int64.Type}, {"Total", Int64.Type}}), #"Grouped Rows" = Table.Group(#"Changed Type", {"Date", "ProductID", "Price"}, {{"Orders", each List.Max([Orders]), type nullable number}, {"Total", each List.Max([Total]), type nullable number}}) in #"Grouped Rows"
