After you have closed the accounts for the fiscal year, you do not longer have access to the result. This is , as told before, balanced into account for year result.
This is normal procedure.
If you forgot to take all your 'normal' reports for the year, you should take them before closing the year.
This is normal procedure for accounting systems.
If you want to restore the fiscal year to be open again, go into the fiscal years and open the year again. And find the journal entry for closing the year. This voucher should be voided in Setup tab, void transaction.
After that, you can take all the reports needed. When you are finished, you can close the year again.
And remember to take your final reports before closing the years in the future.
