What is causing Negative inventory

AI generated answer (using internal Slack threads):

Negative inventory in NetSuite can occur due to several reasons: 1. Fulfillment beyond committed: Depending on your preferences setup, NetSuite can allow you to fulfill beyond committed, which can lead to negative inventory. This is usually controlled under the Fulfillment section located in Accounting Preference - Order Management. 2. Transaction deletion: If a transaction related to an item is deleted, it can cause the inventory count to go negative. The best way to identify this 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. 3. Multi-location inventory: If Multi-location inventory is turned on after the account was already active, it can cause discrepancies in inventory count, leading to negative inventory. This can be fixed using a Distribute Inventory transaction. Please note that while there are ways to prevent negative inventory, such as using a SuiteBundle, these may not always work in all scenarios, such as during Sales Item Fulfillment. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
