If you are an invoice handler, you do not have the option to approve or reject an invoice. Instead, you see the option to "Pass Along" the invoice for the next approver.

Click this button to send a notification to the next individual in the approval chain that needs to take action. Unless this button is pressed, the invoice cannot be approved or rejected.

Once the invoice has been passed along, a memo is generated on the screen; click HERE to return and view the line item
