Help with joining tables



I would like to join two tables using different field matching combinations so that if one matching does not return a result, the other matching is used.


Is that possible?


E.g. I want to join Table1 with Table2 by matching Field1ofTable1 with Field1ofTable2 but if there is no match in a specific row, I want to perform a matching between Field2ofTable1 and Field2ofTable2. So basically, I want two lines that join two tables in the Manage Relationships which both should be active.

Hi @UsePowerBI


You can create a measure which dynamically change the relationships.

I think in manage relatiohship/model tab you can't do that. But obviously you want to use these relationship to calculate something and drag to table/visual, so would suggest you create virtual relationship in the measure with condition.

You can use TREATAS dax.


Please let me know if above helps or explain more what is your objective behind this.

@UsePowerBI , if you want both of them to join, you can use the concatenated column in both tables and join


key = [Field1] & "-" [Field2]


and join on key.

If you do different relation you can create active inactive relation and use userelation
