Could you please keep me in the loop? I am researching different CMS and eCommerce solutions and I was leaning towards Drupal + Ubercart, but if we can't auto import xml or csv files and update existing records then it won't work for us since we are an online store with 16k+ products. I am able to import via Node Import, haven't tried the Node Import via Cron yet, but we will need the import process automated. I don't understand why the task to update records is so difficult as opposed to inserting them since a unique identifier, SKU, is required for product nodes. If it is difficult then maybe the Ubercart product node does not comform to Drupal conventions? I also found it confusing that the product content type didn't list it's default fields with the custom fields I created for product. I doubt we could wait 7 monts for the update functionality; I'll need to find or create a solution if we're going to use Drupal + Ubercart. Any insight or advice would be appreciated. Thanks!
