Accounts Payable

A posted invoice's number may be changed, so long as the invoice is not in a "Paid" status

1. Navigate to Financials>Accounts Payable>Invoice Processing>Modify Invoices

2. Click Define to fill out the Journal Information and Invoices to Modify headers to find your invoice

3. Click Update to show the fields available to modify 

4. Click Accept

5. Click Return to initiate the Output process

6. Choose any output and click Ok to confirm changes

Fields that are available for maintenance vary depending on whether the invoice is unpaid or paid; when an invoice is paid, you can only update the purchase order number, voucher number, department/location code, comments, and description.
