Submit a new and unique ID that you've never used before
In this article
Why this issue is happening
A product that you recently submitted was previously submitted with the same unique ID in the same language for the same country.
How to fix your issue
Each new product that you submit needs a unique ID. We recommend that you use the product's SKU, and reuse that same value each time you submit the product.
Tip: If your unique IDs can be extracted automatically from your data, you can set up a feed rule to change the
ID [id] attribute values in either primary or secondary feeds. The ID rule allows you to bulk update your feed to make sure that each of your products has a unique value for the
ID [id] attribute.
