Vouchers may be voided by using the 
/ 
buttons in the voucher register. The voucher is opened ad normal, except that the notepad defaults to the “Void Reason” and a “Void” button is included.
A reason for the voiding must be inserted in the voucher notepad before the voucher can be voided by clicking the 
button.
When a voucher is voided, the system checks whether or not any commission invoice entries have been generated for that voucher and, if so, automatically creates the necessary credit note reversals.
Vouchers that have receipt allocations cannot be voided (a receipt indicates the validity of a voucher)
