How can I check why an invoice was adjusted?

Invoices that were adjusted but approved are flagged with an icon under the Approved/Paid tab. If there is a comment icon displayed under the Reason column, you can click on it to quickly see the adjustment reason and any additional comments entered by the reviewer. 

This window displays the reason for the adjustment to the invoice as a whole and any other notes added by the reviewer (if applicable). 

To check for adjustments made to individual line items, click Close in the bottom-right corner of the window and then click on the invoice to view its details page.

Adjusted line items display the reason, description, and any reviewer comments in a box (see image below):
