is it possible to batch update/overwrite sales orders through csv

AI generated answer (using internal Slack threads):

Yes, it is possible to batch update or overwrite sales orders through CSV in NetSuite. You can use the CSV import feature in NetSuite to perform this operation. When using CSV import, you can specify the Line ID to indicate which lines you're editing versus adding. This will still be an "update" operation if the sales order already exists, rather than an "add or update". Another option is to use the SuiteSolutions CSV Integrator, which NetSuite has now made free. This tool can help you manage large-scale data updates more efficiently. For specific updates like changing the tax code/tax rate for multiple lines on a sales order, you can also use CSV import. You just need to get the line number or line sequence number in a saved search and include it in your CSV file. Remember, when performing such large-scale updates, it's crucial to ensure your data is correctly formatted and backed up to prevent any data loss or corruption. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
