I had some trouble uploading items for one of my customers into the v7 catalog now whenever I log into the portal I have over 1000 items that are 'invalid'. Is there a way to delete these without clicking the check box and selecting delete on every item??
I ran into the same issue last year where I had to open a ticket with the Assortment Operations Support team and worked with them to clean up the validation errors. Our errors were due to missing or incomplete data for trading partners that we no longer do business with. I can't speculate that it might be the same issue for you, but their support team helped clean our assortment catalog.
