An amortization schedule isn't being prepared on the secondary book, how do I fix this so that it creates one.

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that the issue of not being able to prepare an amortization schedule on the secondary book in a multi-book environment is a known limitation in NetSuite. One workaround suggested in the threads is to manually create a book-specific Journal Entry (JE) that replicates the General Ledger (GL) impact changes that happen on the bill when you fill in the Update Amortization window to create a secondary book amortization schedule. Here are the steps to do this: 1. Create a book-specific JE that replicates the GL impact changes that happen on the bill when you fill in the Update Amortization window to create a secondary book amortization schedule. 2. Set the GL lines on the JE to be what they need to be for the ending GL impact to be correct. 3. Fill in the Name (vendor), Amortization Template, Start Date, and End Date on the applicable line. The end result is you get two identical amortization schedules, one in each book, just like you get if you fill in the Update Amortization window. They just end up originating from two different transactions rather than all from the bill. Please note that this is a workaround and might not be the best solution for all use cases. It's also important to note that all of the periods that you will be amortizing TO have to be open. So if your amortization period is for 10 years, you have to have all of the next 10 years open in order to set up the amortization schedule. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
