I can't use an account in a particular currency in NetSuite - how do I fix this?

AI generated answer (using internal Slack threads):

In NetSuite, once a currency is assigned to an account and transactions are posted, it is not possible to delete or change the currency. This is because the currency field becomes greyed out and uneditable. However, there are a few workarounds you can try: 1. Create a new account without any currency and inactivate the old one. This is the most straightforward solution. You can create a new account with the desired currency and then inactivate the old account. This will not affect any existing transactions. 2. Use the 'Allow GL Account Changes' preference. Under Accounting > Management Preferences, there is an option to 'Allow GL Account Changes'. This allows you to change the GL account on items going forward, without affecting closed periods. After enabling this preference, you can fix the items you need. For back periods, you can always fix the backend with a single journal entry just to clean whatever transactions are needed. 3. Use a sub-account of the desired currency. If you have a bank account in the desired currency, you can create a sub-account of this bank account denominated in the currency you want to use. Then, transfer the amount at the relevant exchange rate out of the main account. NetSuite does not restrict sub-accounts to the currency of the parent account. Remember to test these solutions in a sandbox environment before implementing them in your live account. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
