I have a data table like this:
| Product | Date (month 1) | Month 1 Rev. | Date (month 2) | Month 2 Rev. | Date (month 3) | Month 3 Rev. |
| Apple | 1/1/2022 | 4658 | 2/1/2022 | 599 | 3/1/2022 | 6546 |
| Orange | 1/2/2022 | 1646 | 2/2/2022 | 5646 | 3/2/2022 | 254 |
| Kiwi | 1/3/2022 | 5494 | 2/3/2022 | 6546 | 3/3/2022 | 545 |
I want to transform it like this:
| Date | Product | Rev |
| 1/1/2022 | Apple | 4658 |
| 1/2/2022 | Orange | 1646 |
| 1/3/2022 | Kiwi | 5494 |
| 2/1/2022 | Apple | 599 |
| 2/2/2022 | Orange | 5646 |
| 2/3/2022 | Kiwi | 6546 |
| 3/1/2022 | Apple | 6546 |
| 3/2/2022 | Orange | 254 |
| 3/3/2022 | Kiwi | 545 |
Is it possible to achieve this by pivot/unpivot? I have tried to create the secnd query for each month and then append 12 queries into one query. It works but I am wonderiing if there is more effective way to achieve this. Appreciate your insight!

Hi,
Try following M code.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WciwoyElV0lEy1DfUNzIwMgIyTcxMLYCUEULE1NISSBojBMxMTcyUYnWilfyLEvPSIfqNYJKGZkBJkH64iClExBghYmRqAtbvnVmeCdZtDFdrYmkC1m2MYhlIN5IaU6XYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Product = _t, #"Date (month 1)" = _t, #"Month 1 Rev." = _t, #"Date (month 2)" = _t, #"Month 2 Rev." = _t, #"Date (month 3)" = _t, #"Month 3 Rev." = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Product", type text}, {"Date (month 1)", type date}, {"Month 1 Rev.", Int64.Type}, {"Date (month 2)", type date}, {"Month 2 Rev.", Int64.Type}, {"Date (month 3)", type date}, {"Month 3 Rev.", Int64.Type}}),
#"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Product"}, "Attribute", "Value"),
#"Added Index" = Table.AddIndexColumn(#"Unpivoted Columns", "Index", 0, 1, Int64.Type),
#"Added Index1" = Table.AddIndexColumn(#"Added Index", "Index.1", 1, 1, Int64.Type),
#"Merged Queries" = Table.NestedJoin(#"Added Index1", {"Index.1"}, #"Added Index1", {"Index"}, "Added Index1", JoinKind.LeftOuter),
#"Expanded Added Index1" = Table.ExpandTableColumn(#"Merged Queries", "Added Index1", {"Value"}, {"Added Index1.Value"}),
#"Added Custom" = Table.AddColumn(#"Expanded Added Index1", "Custom", each Number.IsOdd([Index.1])),
#"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([Custom] = true)),
#"Renamed Columns" = Table.RenameColumns(#"Filtered Rows",{{"Value", "Date"}, {"Added Index1.Value", "Product#(tab)Rev"}}),
#"Removed Other Columns" = Table.SelectColumns(#"Renamed Columns",{"Product", "Date", "Product#(tab)Rev"})
in
#"Removed Other Columns"
Thank you.
@Dinesh_Suranga I made it! please ignor my previous post. I have figured it out by following the transformation steps you wrote. Thank you so much!
Thank you so much! Will try the code next week and let you know.

Thank you.
Hi @Dinesh_Suranga , I am new to PBI and have no code skill. Would you explain the code step by step and mark out where should I edit with my own source/table/field name?
