You can only void those vouchers that have an “Open” status. Warning: Voiding a Voucher is irreversible!
To Void a Voucher:
1. From the button bar, click Action, and select vouchers to display the Voucher Entry screen.
2. Enter the number of the voucher you want to void. If you are not sure of the correct voucher number, use the F8 key or the Look-up Button. To set a filter, click Voucher Filter.
3. Once the voucher is displayed, click Tools and select Void Voucher. The following screen appears.

Orion automatically defaults to the current Accounts Payable period for creation of the General Ledger transactions. You may change the period for the any GL transactions that will be created from the voided voucher.
4. Once you have specified the General Ledger period, click Void Voucher and Orion voids the voucher. The voucher Adjustment Register shows a history of the voided voucher’s values, status, period and year voided, and reason (if one is entered). To print this report, click Print Register.
5. If you are sure you want to void the voucher, click “Void Voucher;” if not, click “Cancel.”
