how to categorize lot number per year

AI generated answer (using internal Slack threads):

To categorize lot number per year, you can use the Lot Numbered Items feature in NetSuite. When creating an Assembly item, you can select "Lot Numbered" as the costing method. This will allow each lot to have a specific cost and can be used to categorize lot numbers per year. For generating a report that shows the quantity on hand per lot number per item as of any selected date, you may need to create a transaction saved search or use SuiteQL if you are comfortable with it. There is a Suitelet developed by Tim Dietrich that can be modified to get a report like this. Here is the link: https://timdietrich.me/blog/netsuite-inventory-balance-history-suitelet/ Please note that using lot numbered items can complicate some processes and code, as they behave almost exactly the same as serialized ones. You will need to manage inventory details and when it comes to invoicing, you may have to create an invoice directly from the sales order. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
