Remove Duplicates NATURALINNERJOIN

[flaviocarvalho]

Hi,

When I join 2 tables, I am receiving duplicate values, because in same cases for the same entry I have 2 values. I would like to know, at the end of joining, if I can make distinct, and get only one.

Join = 
VAR A =
    SELECTCOLUMNS (
        TableA,
        "An", RELATED(Advertisers[An]),
        "Key", FORMAT(TableA[Key],"string")
    )
VAR B =
    SELECTCOLUMNS (
        TableB,
        "idAn", TableB[IdAnunciante],
        "NameAn", TableB[NomeAnunciante],
        "Key", FORMAT(TableB[KeyMkt],"string")
    )
VAR Result =
    NATURALINNERJOIN( B, A )
VAR Dist = SUMMARIZE(Result, [IdAn] , [NameAn], [An] )
RETURN
    Dist

Result (In same cases I get 2 entrys):

IdAn	NameAn	An
1153	XPTO	TesteXPTO
1153	XPTO	XPTO

What I want (I just want one entry, regardless of which entry is):

IdAn	NameAn	An
1153	XPTO	XPTO

or

IdAn	NameAn	An
1153	XPTO	TesteXPTO

I need to do this with DAX, because tableA as more than 100M entrys

Hi @flaviocarvalho ,

Has your problem been solved?

If not, do you mind sharing your .pbix file? Or show me the sample data of TableA, TableB and  Advertisers.

Or you can use table visual to get the table.

Or create another table.

'Sheet2' table is your 'join' table.

Creating another table solved the problem. The problem was that I need a Many-to-One connection to another table.

Hi @flaviocarvalho ,

Try to use MAXX() function.

Join = 
VAR A =
    SELECTCOLUMNS (
        TableA,
        "An", RELATED(Advertisers[An]),
        "Key", FORMAT(TableA[Key],"string")
    )
VAR B =
    SELECTCOLUMNS (
        TableB,
        "idAn", TableB[IdAnunciante],
        "NameAn", TableB[NomeAnunciante],
        "Key", FORMAT(TableB[KeyMkt],"string")
    )
VAR Result =
    NATURALINNERJOIN( B, A )
VAR Dist = SUMMARIZE(Result, [IdAn] , [NameAn], "An", MAXX(Result, [An]) )
RETURN
    Dist

Hi @v-lionel-msft ,

I think we are close. My original table without MAX is:

IdAn	NameAn	An
1153	XPTO	TestXPTO
1153	XPTO	XPTO
1164	Yee	Yee
2154	Whiskey	Whiskey

Now the result is the following:

IdAn	NameAn	An
1153	XPTO	Whiskey
1164	Yee	Whiskey
2154	Whiskey	Whiskey

But I need the Max / Min "An" of each ID, like this:
( I tried Maxx(values(Result[IdAn)) but cannot find the table )

IdAn	NameAn	An
1153	XPTO	XPTO
1164	Yee	Yee
2154	Whiskey	Whiskey

@flaviocarvalho , See if this can help

At the end of your code

VAR Dist = SUMMARIZE(Result, [IdAn] , [NameAn],"An" , max([An]) ) // or use min
RETURN
    Dist

Hi @amitchandak , I tried to put a Max or even a filter with count, but I always have the error "Cannot find name [An])". I think it had to be something like Max(TableName[An]), but it also doesn't works, because doesn't accept Max(Result[An])
