Select Authorisation from the side menu, this will show a list of all invoices ready for authorisation.
Use the Approve and Deny buttons to update the authorisation status on the invoice.
The Deny button will also give the option to enter a reason for the denial.
Approved invoices will move onto the Ready for Payment level and denied invoices will go back to the originator.
Once the invoice has either been approved or denied the submission screen will pop up to send the invoice either onto another level of authorisation or Ready for Payment to be put into an interface batch.
