I am using feed importer to bulk import the nodes in a drupal site. I have created a custom content type named Product. This content type has CCK fields which are linked with a taxonomy.
I am using CSV files to import the data. If I put a different(invalid) value in one of the field and that is not present in the vocabulary(term in the taxonomy), it creates a new term.
I want to block the creation of the new taxonomy term as it might create some invalid term in my site.
