why do dropship items show negative sale

AI generated answer (using internal Slack threads):

In NetSuite, dropship items may show negative sales due to the way the system handles Item Fulfillments. When you fulfill a quantity of 1, it is actually subtracting it. This is because the system is taking it from one account and transferring it to another. This can result in multiple lines in your search, and the naive view will show a negative number. This is similar to how Transfer Orders are handled. In the case of dropshipping, you're not really purchasing the inventory, so you wouldn't receive the items into your warehouse. Some users have found that setting up another location with $0 cost buying/selling can somewhat work, but it might even need its own subsidiary to fully delineate the accounting side. Negative inventory can occur if your preferences allow you to fulfill beyond committed, which can lead to negative inventory. Transaction deletion can also lead to this issue. The best way to find the culprit is to look at the item record and trace back through the history of the related records to see where things stop making sense. If the inventory is negative, then the item cannot be fulfilled. Therefore, if you see fulfillments at a time when the inventory appears that it would have been negative based on the history then you can expect something was deleted. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
