I would like to insert products directly into the product table and manage the Category and Subcategory relationship through SQL instead of the user doing this through the UI. I have figured this out as far as mapping the values and foreign keys etc. however I have no idea what the GUID field is for. I know it is required as it is set for non null. I inserted a new category directly into the table and used an existing CategoryGUID value and it appeared to work. Can someone explain this value what it means and let me know if what I am trying to do is possible?
Thanks
