Combination article number and related article number...

Error:

The combination article number '{0}' and related article number '{1}' is used several times.

Explanation:

When importing related articles, a related article number (RelatedArticleNumber) is linked to an article number (ArticleNumber) of the main article.

The combination of these two articles may only occur once in the import file. In this error message, the combination occurs several times.

Solution:

Find the duplicate combinations of the related article number (RelatedArticleNumber) and article number (ArticleNumber) and delete them so that the combination appears only once in the import file.
