What this means

You already have a product on this GTIN. One GTIN identifies one product. That is the whole of what a GTIN is for.

Why it usually happens

A second import of the same row, or a variant that should be a batch of an existing product rather than a product of its own.

What to do

Open the product that already holds the GTIN and edit it. If the two really are different products, the new one needs a GTIN of its own.
