Is it a problem to modify the address of a past invoice if a mistake was noticed after the billing period?

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that modifying the address of a past invoice, whether it's a billing or shipping address, can be problematic if the invoice falls within a locked or closed accounting period. In NetSuite, you generally cannot make changes to an address – whether Ship To or Bill To – if the transaction is already in a closed or locked accounting period. Even if you have the "Allow non-GL changes" option enabled for the period, the system may not save the update. This is because changing the address on a transaction is considered Tax Relevant and even if there's no net change, it's not allowed. However, there are some exceptions. If the address change does not affect the tax nexus, you might be able to change it. But if the system keeps reverting to the prior address without warning, it could be due to a script running in your account that reverses it to the original address. In such cases, you might need to add a custom address instead of updating the existing one. Custom addresses do not store to customer records and only get stored with transactions. But if this doesn't work either, you might need to investigate further to identify any scripts or settings that could be causing the issue. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
