Why can't I select my new Statistical Account in CSV imports for a Vendor Bill's Expense : Account sublist field mapping's default value?

AI generated answer (using internal Slack threads):

The reason you can't select your new Statistical Account in CSV imports for a Vendor Bill's Expense : Account sublist field mapping's default value is because not all fields are available for CSV import in NetSuite. This is a known limitation of the system. In some cases, certain fields may not appear in the CSV import field mapping, even though they are present in the entry forms. This is because these fields are not applicable for CSV import, as per SuiteAnswer 29846. However, these fields are usually available for Mass Update. So, you might want to consider using the Mass Update feature as a workaround for this issue. Please note that this is not an enhancement or a bug, but a standard feature of NetSuite. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
