Error using RELATED

[elflakoconk]

Hello everyone, I have searched all over the forum and I have not found an answer that will solve me.

I'm working with Direct Query, I have 2 tables:

The link field is Phone and as you can see it is many to one. I want to insert a column in A that indicates when the same value is set to B.

I tried RELATED and the resutlado is this message: "The column 'B[Phone]' either doesn't exist or doesn't have a relationship to any table available in the current context."

Even (allows me) by changing the relationship one by one, the same error appears.

I've tried other formulas that I've found on the internet without solving this.
Thank you.

Hi @elflakoconk ,

You can create a measure as below:

Measure = 
VAR _btelefono =
    CALCULATE (
        MAX ( 'B'[Telefono] ),
        FILTER ( 'B', 'B'[Telefono] = MAX ( 'A'[Telefono] ) )
    )
RETURN
    IF ( NOT ( ISBLANK ( _btelefono ) ), "Si", "No" )

Best Regards

Thank you very much, this worked!!! The Microsoft team told me that interactions with DirectQuery may present some flaws with SQL Server, in my case it happened, but this is resolved.

Thanks a lot.

If you want to use related , try this

Column = 
VAR _value=MAXX(FILTER(B,RELATED(B[telefono])),B[value])
return if (ISBLANK(_value),"No",_value)

@elflakoconk , Related you can use in 1- M relation on M side.

you can also move data like this from on table to another

City Name = maxx(FILTER(geography,geography[City Id]=Sales[City Id]),geography[City]) // New column in sales table in my case

Minx/maxx/sumx depend on need
