If you have a full multi-book module in NetSuite, when you do the step - Create Amortization Journal Entries, it doesn't show GL impact 2 books at the same time. Why?

AI generated answer (using internal Slack threads):

In NetSuite's multi-book accounting, the "Create Amortization Journal Entries" step does not show GL impact for 2 books at the same time due to the way the system is designed. The primary book and secondary books are treated separately in the system. When you create a transaction in the primary book, it is automatically replicated in the secondary book(s). However, the amortization schedules for these books are handled independently. This means that when you update the amortization schedule for a transaction in the primary book, it does not automatically update the schedule in the secondary book(s). The "Update Amortization" button is available only when you view the saved transaction record. This button opens the Update Amortization page where you can modify the amortization schedule, its start and end dates, and check or clear the Residual box for secondary accounting books. This is the only way to modify the schedules in secondary books. If you want to automate the update amortization step for secondary books, you might need to create book-specific Journal Entries (JEs) based on the amortization template and dates filled in on the bill. Then link the JEs back to the original Bill so you have references all on the originating transaction. Remember, the premise of secondary book is based on modification of item settings, thus expense line has not much to do with it. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
