the reason of lot quantity for item in negative

AI generated answer (using internal Slack threads):

In NetSuite, negative inventory can occur due to a variety of reasons. Here are some of the potential causes: 1. Fulfillment beyond commitment: 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 to go negative. The best way to identify if this is the cause 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. Inventory adjustments: If inventory adjustments are not done properly, it can lead to negative inventory. For example, if you have a bin with -12 on hand and you bring in 6 items into it, you will still have -6 items in the bin. If you then adjust the inventory of the -6 lot number by 6, the lot number will no longer appear in inventory detail but the location on hand will now show 12. Remember, if your inventory is lot numbered, NetSuite will not allow negative quantity unless there are some irregularities in the transactions or adjustments. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
