when doing a CSV update in NetSuite, does the custom form I specify force my existing data to use that form?

AI generated answer (using internal Slack threads):

When doing a CSV update in NetSuite, the custom form you specify does not force your existing data to use that form. The form that is picked in "Advanced Options" during the CSV import is only for NetSuite to map the fields. If you are updating the record, it will still use the original form. This behavior is confirmed by multiple users in the provided threads. One user mentioned that this was an enhancement request (126956) in NetSuite. Another user suggested that the form selection during CSV import used to affect the form of the transaction record in the UI around 2010-2011, but by 2019, this was no longer the case. In the case of updating custom records that have more than one custom form, you would need to do separate CSV imports for each form. However, it's important to note that the form selection during the CSV import will not overwrite the selected custom form for that record. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
