Fixing the 'values not unique' issue

Issue

id'/'gtin'/'ean' contains values that are not unique

What does this issue mean?

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?

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.

2. If the items are two different variants of the same product, you need to change the identifiers in your import file.
