How to retrieve a value from a table by passing a measure value

[Prima_]

Hi, 

I find 'Most used product' ([Sub_Product Name]) using a measure from the values in Product Table.
I need to find out if the stock is available ([AvailableOrNot]) for this Sub_Prodcut from another table 'Stock'.

Here's the scenario:

Product Table has
[Product Name], [Sub_Product Name]
A A1
A A2
A A3
B B1
...

Stock Table has

[Product Name] [Sub_Product Name] [AvailableOrNot]
A A1 Not Available
A A2 Available
A A3
B  B1

...

Let's say, the Most used product is A2 ----> This is displayed in a Card Visual.
I want to show AvailableOrNot in another Card Visual.
How to write a measure to retrieve 'Stock'[AvailableOrNot] field from Stock Table where 'Stock'[Sub_Product Name] = [Most used product]

Thank you.
