Serial number for each item I am making a book rental cum selling site. I have planned to use Drupal Commerce for it. But tracking the item is simply not possible &amp; so that I am trying to find the solution for assigning serial number for each number of items(attributes) for drupal commerce product.

Like I am having a BOOK &amp; it has 10 copy, so I want to keep one unique serial number for each copy.

If somebody have any idea about this then please help.
I would implement this by first creating a Book Product (Non-Fiction) and issuing a specific sku number for each separate Book Title that I would introduce as a specific product. Combining this with the http://drupal.org/project/commerce_stock module might be useful in allowing unique skus per book but than also having quantity of books in stock for multiple copies.


Ender's Game (10 copies according to commerce_stock) SKU #00000001
Dune(30 copies according to commerce_stock) SKU #00000002
