I want to update an invoice. what field map in the CSV import is for line id ?

AI generated answer (using internal Slack threads):

The field to map for Line ID in the CSV import when updating an invoice is "Order Line". This field is used to identify the specific line item on the invoice that you want to update. In the field mapping page, you should map the "Line ID" from your import file to the "Order Line" field in NetSuite. This will allow NetSuite to correctly identify and update the corresponding line item on the invoice. Please note that the "Order Line" field may not have a key icon next to it in the import mapper. This is normal and does not affect the import process. Also, it's recommended to use the multiple file option when importing, which can help to reduce possible conflicts and errors. One file should contain the header information, and the other should contain the line level data with a reference of the external id from the header file. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
