all new item created in netsuite fall under non serialised but why non serialised inventory is having current serial number and sequence starting number default to P0000000

AI generated answer (using internal Slack threads):

In NetSuite, when you create a new item, it defaults to non-serialized. However, the fields for 'Current Serial Number' and 'Sequence Starting Number' are still present and default to 'P0000000'. This is because these fields are part of the item record structure in NetSuite and are not removed or hidden based on the item's serialization status. Even though these fields are present, they do not affect the functionality of non-serialized items. They are simply ignored when the item is non-serialized. The 'Current Serial Number' and 'Sequence Starting Number' fields are only relevant and used when the item is serialized. If you are seeing these fields populated for non-serialized items, it's likely because they were previously serialized items that have been converted to non-serialized, or the fields were populated manually or through an import process. Remember, changing an item from non-serialized to serialized or vice versa is not a simple process in NetSuite. It requires creating a new item with the desired serialization status, as an inventory item and a serialized item are considered different item types in NetSuite. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
