There are a few reasons why you may want to retire a SKU on your Walmart Seller Center. Perhaps you are no longer able to list this brand to Walmart. Perhaps you have a different SKU using the same UPC and you need to retire this product.
If you've seen an error from Walmart for a SKU that you're trying to list that says, "Unable to complete the product data setup process. Unable to override sku because there exists another source product from the same seller/org id.", you're in the right spot!
Walmart only allows one SKU in the Seller Center per UPC. For this reason, if you already have a SKU in your Walmart Seller Center for a given UPC then you want to remove that SKU in order to list another SKU with the same UPC.
