Assign values from one filter to another filter on the basis of selection

[Shubham_D]

Hi ,

I have filters  UNIT1 and Filter2 and UNIT3 
I am selecting 'A' in UNIT1 and XYZ in Filter2.

Now, there are multiple values corresponding XYZ  in UNIT3 

Requirement : If 'A' selected in UNIT1 and selecting XYZ in FIlter2 then 'A' should get enabled in UNIT3 automatically

How we can achieve this ?

NOTE : UNIT1 and UNIT3 are not in one table.

Rgds,
Shubham
