I am starting to delve into importing around 25K items from our existing POS/Inventory system into NAV. I have the routine down for the basic data fields, with only the item images and attributes being stragglers. I have asked the question about new image imports in a separate post. As for item attributes, I realize there is a more complex table relationship behind the scenes --- attributes, their possible attribute values, and those links to the items themselves. This post I ran across on here is from 2017, so it might be dated --> But it sounds as if it's not possible to import in these attributes via the API, OData, or SOAP. Is this still the case?
What I'm picturing is already having the item attributes and their possible values pre-defined in NAV. So that when I'm importing in new items I can then cross-reference things. Anyone have any insight into how to make this happen?
