There are multiple items that have the same identifier. Identifiers such as ID, GTIN, and EAN codes should be unique for every item.

### How do I solve this issue? <a href="#id-01jpm79tvbsrqez49m7rg1yqh4" id="id-01jpm79tvbsrqez49m7rg1yqh4"></a>

There are two ways to solve the error:

1. If the items that share the identifier are the same item, you can use a [deduplicate items rule](https://app.gitbook.com/s/u8whzIfip72Kvn3M1bsc/rules-bulk-edit-and-enrich/how-to-use-actions-then-in-rules/rule-action-remove-duplicate-items).
2. If the items are two different variants of the same product, you need to change the identifiers in your import file.
