A Voucher is Approved by having a Voucher Approved By name attached.
Generally, a Voucher must be Approved before an AP Invoice or Credit can be created from it. The Control Parameter 'Approve Voucher before Invoice' ' of set to No, allows invoices to be created from Unapproved Vouchers, but only from within the Enter Job Purchases screen.
On the Header tab of the Voucher, three Approval buttons are provided. The related Control Parameters and Admin Function settings may restrict which of the three buttons are accessible for the logged in user.
Once a Voucher is Approved it becomes Read Only, and cannot be changed. Users with the Admin Function 'Unapprove Vouchers' may Unapprove a Voucher using the Unapprove button which will be displayed.
When a Voucher has been turned into an invoice or credit it cannot be Unapproved or changed.
