If there is a price discrepancy between the invoiced price and the price in Hybrent, the item description will be in red as will the price of the item.
Save in the upper right hand corner to save the invoice. Follow your usual procedure to deal with your vendor to investigate the price exception.
If the price change is a vendor error, adjust the price in the Invoiced Unit Price column when the new, correct invoice is sent by the vendor.
If the price change is a valid price change, continue on in the workflow and update the item price in the item catalog.
