SKU specifications

SKU specifications are necessary to be able to choose the SKU, that is, the variation of the product. Example: Color, Size, Voltage. The SKU Selector can be found in the search result or on the product page.


If you wish to implement color variation in your products, we recommend you do not use SKU specifications. Instead, see this tutorial about How to implement product color variation.


VTEX Admin says that if a new SKU Specification field is created, all the SKUs associated will be deactivated. However, if created, products will keep activated.
