Manufacturer GTIN is not unique: already used in assortment...
Error:
Manufacturer GTIN {0} is not unique; it is already used (in the existing assortment) at article {1}.
Explanation:
The manufacturer GTIN is not unique. The import file contains an article with a manufacturer GTIN, which already appears with another article in the existing assortment. That other article does NOT occur in the import file, but it does occur in the EZ-base data.
Solution:
The manufacturer GTIN of each article must be unique. Check the GTIN mentioned and see to which article the number belongs. Correct this number in the import file or in the database.
