Wont redirect to variations without referencing node displays

From what i can tell the barcode scanner rules will only work if there is a reference from a product display to the product variation...

i made a view to intercept the variation in order for it to have a page. i wanted on scan to go to /product/[sku]. so i didnt need for the variation to be referenced to a node display as im just showing the variation...

well seems the sku cant be found untill i make a product node display and reference the variation. then on scan of the same barcode it will go to the view i made.

i had wondered if its the code at bottom of the .module file of ..

foreach (commerce_info_fields('commerce_product_reference') as $field) {

thanks
