You have to change the relationship via a combination of CALCULATE and USERELATIONSHIP. But be careful where you do it. RELATED must work AFTER the relationship has been activated, not before.

    Thanks Anonymous 

    Can you link to an example of this? I tried USERELATIONSHIP with no joy.

      Using RELATED(TABLE) is tricky with inactive relationships. Here's the code you're after.

       

      New Table = 
SELECTCOLUMNS(
    'Fact',
    "Value For Column 1", RELATED( Dim[Value] ),
    "Value For Column 2",
        CALCULATE (
            CALCULATE (
                VALUES ( Dim[Value] ),
                'Fact'
            ),
            USERELATIONSHIP ( Dim[Column], 'Fact'[Column 2] ),
            ALL ( Dim )
        )
)

      Assumptions:

      1. Fact is the fact table with 2 columns, Column 1 and Column 2. Both join on Column to Dim.
      2. Dim is a dimension table with Column and Value.
      3. The above retrieves the Value for Column 1 and Column 2 for each of of the rows in Fact.

      If you want to know why so, please go to this article and read.
