Periodic Closing Voucher

Hi all,
How to clear the previous financial year account such as sales and taxes entry. and generate invoice id from 1.
in periodic closing voucher i have tried but it is not reflecting in the chart of accounts.
need to close the 2016-2017 financial year account and Generate new sales and taxes entry from 2017-2018.

Or Else i need to Clear the Over all Account except current stock and Item.

I have submitted the PCV but the balance sheet is showing incorrect balances. It isn’t taking the PCV amount into consideration even though the ledger is showing it. Due to this the balance sheet is showing the ‘Previous Financial Year Not Closed’ message and the current year balances are not being picked up correctly.

Same thing here
