Why can't I edit an inventory item's Purchase Price Variance account?

AI generated answer (using internal Slack threads):

The Purchase Price Variance account in NetSuite is a system-generated account that is used to track the difference between the standard cost of an item and the actual cost at which it was purchased. This account is automatically updated by NetSuite whenever a purchase transaction is posted and the actual cost differs from the standard cost. The reason you cannot edit the Purchase Price Variance account is because it is a system account, and NetSuite does not allow direct modifications to system accounts to ensure the integrity of the financial data. Any changes to the Purchase Price Variance are made indirectly through the posting of purchase transactions. If you need to adjust the Purchase Price Variance, you would need to do so by posting a purchase transaction with the correct cost. If the cost of the item has changed, you should update the standard cost of the item in the item record, and future purchase transactions will reflect this new cost. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
