As long as the CFOP approver has not yet approved the Purchase Request (PR), the submitter can go back in and update the CFOP as needed by following these steps: 

1. Find the unapproved PR via the search option, then select that PR to see the details.
   
   
2. Scroll down the page to the "Payment Details" section.
   
   
3. Select Change Cfopa (highlighted below) by the line item(s) you need to change
   
   
   
   
4. On the next screen, select Edit
   
   
   
   
5. Update the CFOPA(s) on the screen as directed, then click Submit
   • You do NOT need to press the Validate button before submitting
   • You cannot change percentages to dollars
     
6. At this time, the CFOP is updated and should route back to the approver (or new approver, depending on updated CFOP).
