Adds a button to the WC edit/new product page that enables generating a SKU (catalog number) in a pre-defined format and length. It is aimed for Woocommerce shop admins who manage a shop with no pre-defined catalog numbers for products.
When adding or editing a product it is common that you do not have a pre-set catalog number for the product. 
This plugin enables you to generate a SKU (catalog number) for the product, with specified format and length. 
It also checks that the suggested SKU does not exist in the database for any other product.
At the same time you can use it to check a SKU number you enter.
Starting on V 1.0.1 you can choose to add automatic SKU for every new product or existing product without a SKU (no need to click a button or select).
You also can select not to generate a random SKU, but write it yourself, and the plugin will check asynchronously if the SKU already exist in the database.
<blockquote>
Tested up to Woocommerce Version 6.0.0
Important! version 1.0.2 and up works with Woocommerce 2.6.0 and up. If you have earlier version of WC please use this plugin version 1.0.1
