Lookup value matching more than one (Index Match)

I have two tables: "Data" and "Report."
The "Data" table consists of columns such as type, id, code, and country.
Meanwhile, the "Report" table includes columns named Item, type, code, and country.
The connection between these tables is established through the type, id, and code columns.
My objective is to extract the id from the "Data" table and incorporate it into the "Report" table, utilizing the criteria of matching type, code, and country.

Report Table:

In Excel I am applying the following formula to get the result:
=IFERROR(INDEX(DATA!$B$3:$B$29,MATCH($B3&$C3&$D3,DATA!$A$3:$A$29&DATA!$C$3:$C$29&DATA!$D$3:$D$29,0)),"")

I am using the below mentioned DAX but it's not working

Desired Result1 =
LOOKUPVALUE(DATA[Id],DATA[Code],REPORT[Code],DATA[Country],REPORT[Country],DATA[Type],REPORT[Type])

Table Report:

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fdDLDoMgEAXQXzGsXQwPQZfUmrYpMY2PTY3//xsyA8WgqQtHkuPNHVkWxoVkJbNf7ieAAf8q8GgMW0tklZgDnLm6TuvrtEEGnKATt88ucr1zI8/cXKYp8D8tOTFWQK2Q57cfjymyOPHoh/MfBZdH7+bBz2GIro5e0BOQbs3SrQmdulNWJy5+xfveJsPQmrauM7xZl+3cZPqxWDo6HpSW3PXV30lFVJ7rRCgjigxb25OqqDJTS/8zuoqt6wY=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Item = _t, Type = _t, Code = _t, Country = _t, #"Desired Result" = _t]),
    #"Merged Queries" = Table.NestedJoin(Source, {"Type", "Code", "Country"}, Data, {"Type", "Code", "Country"}, "Data", JoinKind.LeftOuter),
    #"Expanded Data" = Table.ExpandTableColumn(#"Merged Queries", "Data", {"Id"}, {"Id"})
in
    #"Expanded Data"

In DAX you would similarly use a compaosite key

The problem is that it is not unique - A080840 appears twice. That introduces ambiguity.

Hi,

Write this calculated column formula in the Report table

Column = CALCULATE(MAX(Data[Id]),FILTER(Data,Data[Type]=EARLIER(Report[Type])&&Data[Code]=EARLIER(Report[Code])&&Data[Country]=EARLIER(Report[Country])))

Hope this helps.

Does it need to be DAX or can this be in Power Query?

@lbendlin, Thanks for your reply. If possible to provide the solution both ways(DAX new calculate column and Power query) it will help to understand the Power BI. 

Table Report:

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fdDLDoMgEAXQXzGsXQwPQZfUmrYpMY2PTY3//xsyA8WgqQtHkuPNHVkWxoVkJbNf7ieAAf8q8GgMW0tklZgDnLm6TuvrtEEGnKATt88ucr1zI8/cXKYp8D8tOTFWQK2Q57cfjymyOPHoh/MfBZdH7+bBz2GIro5e0BOQbs3SrQmdulNWJy5+xfveJsPQmrauM7xZl+3cZPqxWDo6HpSW3PXV30lFVJ7rRCgjigxb25OqqDJTS/8zuoqt6wY=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Item = _t, Type = _t, Code = _t, Country = _t, #"Desired Result" = _t]),
    #"Merged Queries" = Table.NestedJoin(Source, {"Type", "Code", "Country"}, Data, {"Type", "Code", "Country"}, "Data", JoinKind.LeftOuter),
    #"Expanded Data" = Table.ExpandTableColumn(#"Merged Queries", "Data", {"Id"}, {"Id"})
in
    #"Expanded Data"
