If you have a SKU in Zentail that uses a product ID that is different from the product ID found on your Seller Center, you may have encountered this Walmart error: "This SKU is already set up with a different Product ID (i.e., GTIN, UPC, ISBN, etc.). If you are trying to change this SKU's Product ID, submit the product_id_override flag in the request."
Here are the steps for addressing this error:
Go to the SKU on your catalog page.
Scroll down on the side bar and find the Walmart card. Click Advanced Options.
Find the Send ID Update and Send SKU Update check boxes.
To update the Product ID for the existing SKU, check Send ID Update; or
To update the SKU for the existing UPC, check Send SKU Update
Click Update or Update & Push.
Once enabled, Zentail will send an update to Walmart to change the SKU's product ID (usually your UPC) to the value you have in Zentail, or to change the SKU for a product ID to this SKU!
You can also set these fields for each SKU using our Import / Export feature! Use the attributes ending with:
(Walmart) Send Product Id Update
(Walmart) Send Product SKU Update
