How do I assign custom attributes to SKUs?

Here are the steps to assign one or more custom attributes to products:

1. Edit the product using the Products > Product Catalog Manager > Product Editor  link. 
   
   
2. Click the Advanced tab at the top of the page.
   
   
3. Scroll down to the Edit Custom Product Attribute section.
   
   
4. Select a custom attribute from Product Attribute drop-down list (e.g., Year)
   
   
   Note: If the drop-down list is empty or the attribute you want doesn't exist, you need to create a new one by going to Products > Custom Product Attributes.
   
   
   
   
5. Specify a value for the custom attribute in the Value field (e.g., 2008).
   
   
6. Specify a Sort Order to control where in the list of custom attributes the attribute will appear, if desired.
   
   
7. You can also make this option visible or invisible using the Visible checkbox.
    
8. Click the Add New Attribute button.
   
   
9. Repeat for each attribute you would like to apply to this product.
