Is it possible to add a field to NetSuite Invoice, which can be edited even when the accounting period is closed.

AI generated answer (using internal Slack threads):

Yes, it is possible to add a field to a NetSuite Invoice that can be edited even when the accounting period is closed. This can be achieved by enabling the 'Allow Non-G/L Changes' permission for the relevant role. Non-G/L changes include modifications to non-accounting fields such as memo, line description, etc. Here are the steps to enable this permission: 1. Navigate to Setup > Users/Roles > Manage Roles. 2. Edit the role for which you want to enable this permission. 3. Under the 'Permissions' subtab, go to 'Setup' and add the 'Allow Non-G/L Changes' permission. 4. Save the changes. Please note that this permission allows changes to be made to non-accounting fields on transactions in closed periods. It does not allow changes to any fields that would affect the General Ledger. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
