New Supplier bank account not getting updated in AP invoices

Summary:

Our client interfaces all Vendor master data from third party system to Oracle Fusion and it includes Vendor bank account as well. After the recent interface run new bank accounts were added to the Supplier site for all the BUs for the Vendor but the AP Invoice installments are still mapped to the old bank account. When we manually add a new bank account from the UI, a message is displayed asking if you would like the existing installments to be updated with the bank account but I am not clear how this works when new bank accounts are added
