Hello Soceir,
The way accounting works any balance will always be rolled over as the opening balance - for example Debtors, if the Debtors balance didn't roll over you would lose track of what you were owed and reports would be wrong.
When choosing your report - Reports>Other Reports>chosen report, you will be able to choose the start and end dates, or select the period, such as 'This Fiscal Year' or 'Last Fiscal Year'. That should generate the current or last years fiscal data.
There does not appear to be a 'Year End' procedure, but you can force a no transactions with a date before the current year, when you have finalised the previous years accounts, by using 'Accounts>Closed-to-date' from the menu bar.
Hope this helps.
