How does NetSuite costing engine work for serialized items that cycle repeatedly within a day. There’s only one item and hundred thousands of serials

AI generated answer (using internal Slack threads):

Based on the conversations, NetSuite's costing engine for serialized items that cycle repeatedly within a day works in the following way: NetSuite uses a specific costing method for serialized items. When an item is serialized, each individual unit of that item is tracked by a unique serial number. This allows for precise tracking of the cost of each individual unit as it moves through the inventory cycle. However, dealing with a large volume of serialized items can be challenging. The native Item Receipt and Item Fulfillment express entry may not be feasible for thousands of serialized items. CSV imports have been tried but found to be inconsistent and challenging for warehouse staff to use. One potential workaround suggested is to use Lot Numbered Items. If you select "Lot Numbered" as the costing method, each lot will have a specific cost. This can get you a little closer to what you want, but it also has its own challenges. For instance, you need to play with inventory details and when it comes to invoicing, you have to create an invoice directly from the sales order. Another suggestion is to consider an intermediate application that creates the user experience you want then talks to NetSuite via a restlet. This could be a node/react application with a dedicated database, and then employ a lambda function to process the data. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******

No my issue is how the costing engine work, as the engine is taking days/weeks to compute
