You can change the relation between an SKU and a Product by editing the SKU, following the steps below.

1. In the VTEX Admin, go to Catalog, or type Catalog in the search bar at the top of the page.
2. Click on All products.
3. In the desired product, click on the down arrow and select the SKU option.
4. In the SKU you want to delete, click on Change.
5. In the Product name (ID) field, in Current Selection, click Remove to disassociate the product currently related to the SKU.
6. To associate the SKU to another product, enter the product name in the Product name (ID) field and click on the desired product. If you prefer, you can click on Advanced Search to search by Name, ID or SKU the new product to be related. Searching for the product by ID or SKU will be more precise for cases where there is the same value for Name in different products.
