How do I lock future periods

AI generated answer (using internal Slack threads):

To lock future periods in NetSuite, you need to navigate to the 'Manage Accounting Periods' page. Here, you will see a list of all accounting periods, both past and future. Each period has a padlock icon next to it. The padlock icon will only appear when the period is active. To lock a period, you need to lock all previous periods first. This is because NetSuite does not allow you to lock a period if there are any open periods before it. Please note that the system does not automatically lock periods. This is a manual process that needs to be done by a user with the necessary permissions. Also, it's important to note that the period record is not accessible via a script. Therefore, it's not possible to systematically lock AR at a specific time. However, you can create audit searches for review before manually locking the period. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
