how do i find the posting period id numbers

AI generated answer (using internal Slack threads):

To find the Posting Period ID numbers in NetSuite, you can follow these steps: 1. Navigate to Setup -> Accounting -> Manage Accounting Periods. This will open the Manage Accounting Periods page. 2. On this page, you will see a list of all the accounting periods. Each period has an internal ID associated with it. This internal ID is the Posting Period ID number. Please note that you can only post Journal Entries to adjustment periods. Other transactions like bills cannot be posted to adjustment periods. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
