how do I reserve an item inventory without decrease the on hand inventory?

AI generated answer (using internal Slack threads):

In NetSuite, you can reserve an item inventory without decreasing the on-hand inventory by using the concept of 'Safety Stock'. Safety Stock is a term used to describe a level of stock that is maintained below the cycle stock to buffer against stock-outs. Safety Stock functionality in NetSuite allows you to reserve a certain quantity of an item. For example, if you have 200 units of an item in stock but you don't want them all being sold, you can set a Safety Stock level of 50. This means that when the inventory level reaches 50, the system will show the item as out of stock, even though there are still 50 units in your inventory. This does not decrease your on-hand inventory, but it does reserve a certain quantity of the item. To set the Safety Stock level for an item, you can go to the item record and enter the desired quantity in the 'Safety Stock' field. Please note that this field might not be visible by default and you may need to customize your form to make it visible. Also, please note that this is a simple way to reserve inventory and it might not cover all scenarios. For more complex scenarios, you might need to use other functionalities like demand planning or supply allocation. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
