Is there a need to modify the program elsewhere?

If the field `products_family` exists in the product's table and the row contains the primary key that has been chosen, then import of that data should work or a message is provided about it not working.

To further test, I would recommend exporting one or more product that already have information in that field to see that it is exported and to provide a sort of example.

There is no other code modification necessary to support that in an otherwise functional system.
