Power BI Relationship between two tables

I have 2 tables T1 and T2 and they related to each other using T1(1-*)T2. 

Now I wanted to show the rows from T1 where I couldn't find atleast one row in T2. 

Using SQL I could write something like this ... 

 

Select * from T1

Left Join T2 on T1.c1= T2.c1

where T2.c1 is NULL

 

But how could I acheive this in Power BI. 

Any Idea would be appreciated. Thanks in advance.

Hi @Anonymous

 

One way is to new a table with EXCEPT Function . The other way is to use Merge Queries in Query Editor. For example:

Is there any way that we can do by just making use of relationships ?

Hi @Anonymous

 

You may try to set the 'Cross filter direction' to 'Both' in relationship.

Thanks @v-cherch-msft

The Cross filter direction to both is not surving my purpose.
