Working With Posted Vouchers After you post vouchers, you may need to revise them. The amount of a voucher may be incorrect, requiring that it be changed before it is paid. The voucher may have been recorded to the wrong period, and you need to void and enter it again with the correct G/L date information. You can make these types of changes after a voucher is posted. Upon completion of this lesson, you will be able to: • Revise posted vouchers. • Delete posted vouchers.
