Trail Balance got changed

1

The Year 2020 was closed and there were no transactions have made against it.

when I regenerate the same report for the same period this year there was a difference!

how I could trace the cause of this?

The same thing has happened, in 2021 TB has been generated, and then after few days, the figure has changed.

what is the possibility that this is a bug, or that accountants have made a mistake?

what is the best way to track it knowing I am using the latest server version 22.6.1

Did you update exchange rates?
You could check the history and look for changes or entries

You may also have updated tax codes revoked by the government instead of inactivating them and creating new ones.
