Please, reconsider that idea again! According to the official documentation - before I enabled Advanced awareness I resettled cross-year settlements according to this information : Enable advanced awareness options parameter before year-end close using the inquiry page - Finance | Dynamics 365 | Microsoft Learn"Follow these steps if your organization wants to use the Enable advanced awareness options parameter before you run the year-end close for fiscal year 2022. NoteThe year-end close for 2021 and earlier fiscal years must be rerun only if new transactions are posted into fiscal year 2021 or earlier. When you complete the following procedure, no new transactions are posted into 2021. Therefore, the year-end close doesn't have to be rerun.Ledger transactions that are settled across fiscal years can remain ledger-settled if they aren't settled against a transaction that was posted into 2022 (the year that's being closed) or later. For example, if you've settled transactions in 2019 and 2020, they can remain settled."
