Before you can Auto Balance the transaction, the From Subsidiary Balance must be the opposite of the To Subsidiaries Combined Balance

AI generated answer (using internal Slack threads):

Based on the conversations provided, it appears that NetSuite requires 4 lines per advanced intercompany journal entry to ensure a balanced general ledger for each subsidiary. This is because each subsidiary is considered a separate legal entity with its own balance sheet, bank accounts, etc. If one subsidiary sends money to another, then one subsidiary becomes indebted to another. If you have the Intercompany AP/AR accounts configured and set as the defaults under Accounting Preferences, you can use the Auto Balance feature for NetSuite to make the offsetting posting for each entity. Then you only need to show the Debit/Credit to Cash, and then select Auto Balance and it should function the same as your legacy system. In terms of transferring balances from one department to another in the Elimination subsidiary, it seems that NetSuite does not allow this without great difficulty. The cleanest way to handle this situation would be to reverse the original journal and book it correctly. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
