Can't merge columns properly

[niekdp]

Dear,

I have a table with exchange rates per day. An example: 

Exchange rate  currency date

1.14                    usd           01/01/2018

1.40                    cad           01/01/2018

0.90                    gbp          01/01/2018
1.15                    usd           02/01/2018
1.42                    cad           02/01/2018
0.88                    gbp          02/01/2018
1.20                    usd           03/01/2018
1.44                    cad           03/01/2018
0.86                    gbp          03/01/2018

So as you can see, the exchange rate to our base currency (EUR) changes per day. 

We also have another table with transactions per day. 
So you can have multiple transactions in different currencies per day.

To merge this colums, I made a key. 
For the exchange rate column it is p. ex: 03/01/2018GBP
In the transaction colum, I also made this key 03/01/2018GBP.

What I want to do is to have the exchange rate from the correct date and currency next to the amount the was paid in the transaction column. But if I merge these columns, Power Bi only shows me the average of GBP.

So I see every time :

01/01/2018GBP 0.88
02/01/2018GBP 0.88
03/01/2018GBP 0.88
Which isn't correct.  Is there somebody who could find the solution for my problem?
(So to see the correct exchange rate per currency per day next to the amount in the transaction column)

Kind regards

@niekdp,

How do you merge column in query editor? I use Merge column feature in Query Editor and everything works as expected. You can paste the following code to Advanced editor of a blank query.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ZcwxDoAgDIXhu3Qm0BY0eBbCgJq4mhjvLwwmr2Hp0D/vK4XESyJH73P2K0GCsmSqbpTE/Xe0qbDfRrn2e97IApoaTUFT1HIGzWyUQYtGS6BFo62g/aV+", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"Exchange Rate" = _t, currency = _t, date = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Exchange Rate", type number}, {"currency", type text}, {"date", type date}}),
    #"Inserted Merged Column" = Table.AddColumn(#"Changed Type", "Merged", each Text.Combine({[currency], Text.From([date], "en-US")}, ""), type text)
in
    #"Inserted Merged Column"

HI @BalaVenuGopal

Thank you for your response.

This is actually in the querry editor it self that I don't receive the right values..

Kind regards
