Subcategories can be defined to override default category record values. For example, you may have a subcategory that is assigned to two different parents and you want to use one page title when accessed through one parent category and a different page title when accessed through a different parent category. When editing a subcategory that exists in two or more locations in the category hierarchy, the More Actions menu includes a menu option to Edit Category Overrides. Clicking this button lets you override default subcategory settings.
Any changes to category override values are stored in the category record in NetSuite. For more information on overrides, see Create Subcategories for a Commerce Category.
