End-of-Period Processing will update all of your Account Balances and set
them for use with Reports etc. Once the End-of Period Processing has been
done no more transactions can be entered for the last period.

  for the Previous Accounting Period have been POSTED.

The System Date can be changed via the Extended Options Menu if you need to
  go back to the Previous period to Post Batches before you continue with the
  End-Of-Period Processing.

  to the prompt appearing on the screen updates all of your historic Account

  Menu.
