when updating a transaction item through a csv import, what field should I use to match the item on the csv to the item on the transaction?

AI generated answer (using internal Slack threads):

When updating a transaction item through a CSV import, you should use the 'Order Line' field to match the item on the CSV to the item on the transaction. This field corresponds to the 'Line ID' on your import file. In addition, you may also need to map the 'internalid' of the main line at the line level. This should help in correctly identifying and updating the specific line item on the transaction. Also, when importing a CSV for a transaction import, if you want to automatically map the item ID to use 'internal ID' instead of 'Name' by default, you will need to manually select 'internal ID' for the first time. After that, you can save your import with mappings, which will remember your ID preference for future imports. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
