What should I do if my SKU is already in the Shopify database?

If a SKU already exists in your Shopify store, new variants using the same SKU will not be added unless they are merged into the existing product. To add new variants later, enable "Merge variants into existing products" in the add feed and map the Variant Group field. Ensure the new variants share the same merge group (such as handle, barcode, or product title). If the SKU is already in use and not meant to match the existing product, change the identifier to a unique value or use another field as the product identifier.
