How to add a unique value to a product?

Question

PHP

Help, please, by solving the problem. Online store on Magento 1.9. In the admin panel, you need to add serial numbers, it is possible in one table, but it is better immediately with reference to a specific product. Further, after the order has got into the admin panel, you need to add your unique serial number to each product and the added number should be removed from the list of available ones. The task seems to be solvable, but there is one thing, but, in the magento order, the product is displayed as a product and its quantity is affixed, but it is necessary that the same products are also separate. I found the serial codes extension, which seems to solve the problem, but the developers are silent. I will be glad to any ideas. Thank you.

Answer 1

It is necessary to create Virtual or Downloadable products, add an attribute and enter this serial number for the product. Again, there is little data, you did not explain what kind of product and what other features there are and how these remaining serials are then used.
