Hi everyone,

I'm experiencing a problem with my data. I have the table 'Outbound' which has Delivery, Freight Costs, Sales and Date fields.
I want to manipulate the Freight Costs column according to Delivery Field.

What I have
Delivery Freight     Sales
S102           $30         $300
S102           $30          $400
S103           $50          $500

What I want
Delivery    Freight    Sales
S102         $0        $300
S102         $30       $400
S103         $50       $500

Please note that I don't want to sum duplicates for the delivery, I want to write one of the duplicate values in freight costs for that particular delivery and make the other one 0 to ensure that the total sum of the column is accurate. Thanks for your help in advance.

Hi @Anonymous ,

This is the Power Query forum. In the Power Query Editor, we use the M language instead of the DAX language. There is a difference between the two. You can check this blog for reference.

My solution is completed in Power Query Editor.

Sample data

1.Select both columns and group by.

2.Select All Rows and click ok.

You get this.

3.Add a custom column. 

Table.AddIndexColumn([Count],"Index",1)

4.Expand the Sales column and the Index column, remove the Count column.

5.Add a conditional column, set if [Index] = 1 then [Freight] else 0.

6.Remove the unneeded columns and rename the custom column. Finally get the result.

You can download the .pbix to check.

NewStep=Table.FromRecords(List.Accumulate(Table.ToRecords(PreviousStepName),{},(x,y)=>if x={} then {{y},Record.AddField([],y[Delivery],0)} else {x{0}&{y&[Freight=Record.FieldOrDefault(x{1},y[Delivery],1)*y[Freight]]},x{1}&Record.AddField([],y[Delivery],0)}){0})

Hi,

If you are only concerned about the sum of the rows you can use this as an alternate way of achieving your goal:
Example data:

1st I created a duplicate query and grouped it:

#"Grouped Rows" = Table.Group(#"Changed Type", {"Delivery"}, {{"Count", each Table.RowCount(_), Int64.Type}})

After this I merged this count to the original:

Now Simply divide the original value with the count to get a row specific value:

Full M:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCjY0MFLSUTI2ABMGSrE6qGImCDFjINfUAEwAxWIB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Delivery = _t, Value = _t, Sales = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Delivery", type text}, {"Value", Int64.Type}, {"Sales", Int64.Type}}),
#"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Delivery"}, #"DeliveryPQ Grouped", {"Delivery"}, "DeliveryPQ Grouped", JoinKind.LeftOuter),
#"Expanded DeliveryPQ Grouped" = Table.ExpandTableColumn(#"Merged Queries", "DeliveryPQ Grouped", {"Count"}, {"Count"}),
#"Added Custom" = Table.AddColumn(#"Expanded DeliveryPQ Grouped", "NewValue", each [Value]/[Count]),
#"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Value", "Count"})
in
#"Removed Columns"

Maybe you can solve your issue by using this method?
