How to filter from two tables with different data input

[vutruong]

I have two data uploaded to BI desktop, they have the same two columns of "Region" and "Area" which have the same content in there, but the number of rows and the content from other columns are different.

What I want is that when I select/filter in "Region" and "Area" columns from Table 1, it also automatically happens in Table 2. For example, I select "Central South" in "Region" column and "Central 1" in "Area" column, then it will be automatically chosen from "Region" and "Central 2" from table 2. 

Can you please help how to do it. Thank you.

Hi,

You should create a master table of Region and Area.  Then create a relationship from the 2 individual tables to the master tables created.  In your visual, the region and area should come from the mster tables.
