What's the impacts if we inactivate tax book

Summary:

We enabled Valuation Method Ledger option for asset module of secondary ledger.

And created one tax book connected to this secondary ledger.

So any assets records will generate accounting entries and post to this secondary ledger.

Now business is considering to disable this tax book because of some reasons.

Because once inactive on field is assigned a date, it cannot be reverted.

So we want to confirm, in our scenario, if we disable this tax book:

1. if we disable from Aug-25, then any transactions happened before the inactive date will impact month end close?
2. is that possible to make the change and ask corporate book to generate accounting entries and post to both primary ledger and secondary ledger?
