I'm trying to import some data to classify certain products but none of my rows are being accepted. I don't have any special characters that I know of, unless - is a special character, in the value. I've also searched for the value within the dimension in adobe analytics and can see the value there to assign a classification to but still no joy.
@LGalliers - Can you provide some sample rows? I'd be interested in seeing the key and related classification columns for a few records. I'd also be interested in any error messages you're seeing telling you that the classifications are failing. This information will be helpful/necessary to help troubleshoot.
