Walmart Publishing Errors - SKU or Product ID Overrides

How to solve the Error from Walmart: This SKU is already set up with a different Product ID (i.e., GTIN, UPC, ISBN, etc.).

When publishing to Walmart you will be required to include a valid Product identifier (Product ID) along with other required fields. If you have listed to Walmart before using  Marketplace Management then you may have already used a Product ID or SKU and those values are present within your Walmart store. Walmart will only allow for duplicate SKUs and will not allow you to use the same UPCs for multiple items. 

Typically Walmart will advise using a Product ID or SKU Override. At this time you cannot perform this action through Marketplace Management and you will need to submit that adjustment request through Walmart directly. 

Using Walmart, you can submit a full Inventory Spec. Template with the override information filled out. This will adjust the Product ID on the "wrong listing" and you can then relist through Marketplace Management with the correct SKU/Product.

Here is Walmart's documentation on this process


You might see an error from Walmart indicating: "The Product ID is already set up with the SKU %s" or "The Product ID is already set up with the SKU Qarth". Unfortunately, this indicates an issue on Walmart's end and it is outside the realm of Marketplace Management. 

  • We advise attempting to publish this SKU at another time. You can also open a Walmart Support Ticket and advise that you're hitting that error with the specific SKU you're publishing. 


Can I just delete the SKU from Walmart and start from scratch?

At this time Walmart does not allow you to delete items instead they allow you to "archive" them. Unfortunately, even if the item is archived the Product ID and SKU will still be seen and referenced. The best option is to perform the Product ID or SKU Override or use an entirely different Product ID or SKU.

The Product ID that is already listed on Walmart does not match the product itself. How can this be corrected?

Walmart is still a fairly new sales channel and while the existing catalog was being built it accepted data from hundreds and thousands of sellers. This might have led to data being incorrectly represented on their page. 

Unfortunately, if the Product ID is not accurate and is already a product being sold by someone else, you will want to open a ticket with Walmart Support advising that the product is incorrect.
