Closure - information on and about

“Closure” is a pick under the Accounting menu. However, I can find no documentation on its usage. While it appears to be straightforward, I like to know where the ship is going before I set sail.

  1. When you execute the “Validate and Lock Movements” is the action absolute? That is, can you unlock the transactions if at a later date a revision of accounting transactions need to be corrected.

  2. When you execute the “Close Fiscal Period” is the action absolute? Again, can it be unlocked if the situation arises.

  3. When you execute “Extract Entries” while optional, is there any setup for the process? Other than a retained earning account in the COA, are there any others needed?

Thanks Frank
