Can't create a new column using related in table in Power Bi

[Analitika]

Hello,

I have question, how I could create a new column using related expression. I used like this: 

I checked - both tables has a relationship but I still can't create that column. I am getting this error:

How I could resolve this issue?

Hi @Analitika ,

The RELATED function cannot be used to fetch a column across a limited relationship.

You can try some DAX like the following:

columns =
CALCULATE(
    MAX( 'result_table'[values] ),
    FILTER(
        'result_table',
        [related_ID] = EARLIER( 'current_table'[related_ID] )
    )
)

OR LOOKUPVALUE().

Best Regards
