why non serialised inventory having. current serial number and sequence starting number

AI generated answer (using internal Slack threads):

In NetSuite, serialized and non-serialized inventory items are treated as different item types. A serialized inventory item has a unique serial number associated with it, which is used to track the item throughout its lifecycle. On the other hand, non-serialized inventory items do not have unique identifiers and are tracked based on their quantity. The current serial number and sequence starting number for a non-serialized inventory item might be present due to a previous conversion from a serialized item to a non-serialized item. However, it's important to note that you cannot remove the serial number from a serialized inventory item, nor can you add a serial number to a non-serialized item in NetSuite. If you need to convert non-serialized stock to serialized and move the stock quantities to the existing serialized item, this would require either custom code or a series of manual steps. One possible approach could be to use an assembly item that is serialized. You could then add the serial number to items you build into a serialized item. Please note that if you're dealing with transactions that impact inventory, such as cash sales, and you're using serial numbers, you must choose which individual item to remove from inventory. This is because each serialized item is tracked individually. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
