Hi @savanah 

 

What you would need to do is to have a table which has got all your Cities values. You would then create a relationship from T1 and T2 to your City Table.


Then you can use the values from your City table to filter both tables T1 and T2.

 

This is known as a star schema, here are more details: Understand star schema and the importance for Power BI - Power BI | Microsoft Learn

Thank you very much for replay  
I was create (cites) table..

but when I make relationships between (citey in T1 or T2) 

the message appears

(you can't create a relationship between these two columns because one of the columns must have unique value 

Hi @savanah ,

 

@GilbertQ asked to create a distinct list of values (Cities) as a dimension table that can be joined to both ends of T1, T2 city columns.

Use City column from new dimension table in your filter criteria.
