how to calculate historical opening balance for inventory

AI generated answer (using internal Slack threads):

To calculate the historical opening balance for inventory in NetSuite, you can use the

Inventory Valuation Detail

report. This report provides a detailed view of the inventory transactions that have occurred over a specified period of time. However, please note that NetSuite does not natively support viewing historical quantity on hand for a specific date in the past. You would need to calculate this manually by summing up the inventory transactions up to the date you are interested in. If you need to view the inventory adjustment history, you can create a transaction saved search of type inventory adjustment. This will allow you to see all the inventory adjustments that have been made. For more advanced needs, you might find this Suitelet useful: https://timdietrich.me/blog/netsuite-inventory-balance-history-suitelet/. It lists all transactions that have had an impact on an item's inventory balance. Please note that if you need to revalue inventory items backdated to a specific date without changing quantities, you might need to use a workaround. One suggested method is to bring the inventory to 0 on a day with no inventory transactions, and then bring the inventory back up to stock at the correct value on the next day. This will change the financials in that period, and you will need to use an appropriate expense account or a holding account for both inventory adjustments. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
