Couldn’t import a duplicated Reference/SKU - Feed.biz (WooCommerce)

You export your products and you get an error message like this one:

Couldn't import a duplicated Reference/SKU (XXX-YYY)

The concerned product is a duplicate, that means that the product reference is present at least twice in the database which is wrong.

Example for duplicate:

You must ensure that each product and each combination has a unique reference as shown on the page: validate your catalog structure.

Action: Correct the duplicated product reference.
