ArticleSequence field has to be filled with a number

 
 
Error:
ArticleSequence field has to be filled with a number.
 
Explanation:
In some cases, an article selection is required that is determined outside of the export from EZ-web, for example in order to make proofs of certain articles.
This can be imported as a catalogue selection. Such a selection is made at the article level. In this way, certain articles can be included or excluded within an article group.
The column ArticleSequence is optional. If you wish, you can enter your own sequence which is used when exporting this catalogue selection.
Enter increasing numbers. The numbers do not have to be consecutive. Alphanumerical values in cells are not permitted as this will result in an error message.
 
Solution:
Make sure that the column ArticleSequence is filled in everywhere and ascending with a number or remove the whole column from the import file.
