How do you change preferred stock levels?

AI generated answer (using internal Slack threads):

To change the Preferred Stock Levels in NetSuite, you would need to navigate to the item record and adjust the Preferred Stock Level field. This field can be found on the header or location level of the item record. The Preferred Stock Level (PSL) is the ideal quantity you want to have on hand (minus the safety stock) to fulfill your daily demand. For example, if you want 50 units of an item in the safety stock, and you need 10 days to receive it on a Purchase Order (PO), and you sell 1 unit per day, your reorder point might be 60, but your preferred stock level is 110. On the other hand, the Safety Stock is the amount you always want to have on hand no matter what. This is the minimum inventory level you want to maintain to avoid stockouts. Remember, the PSL and Safety Stock are related but serve different purposes. The PSL is how many you want to keep in stock operationally, while the Safety Stock is an amount that you always want to keep as a buffer on top of the PSL. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
