Hello Sonia,

In Adagio Ledger, you can close fiscal periods once you have printed the financial statements. Transactions allocated to the closed periods are written to an error batch and are not posted.

In the subsidiary ledgers, there is a setting in the company profile that controls how far "away" from the current date a transaction can be entered without generating a warning.

You'll see this tightened in the Version 9.0 products as they release.
