Within ImageCapture, you can have an invoice re-read or move back one step in the process. You perform both actions using the 'Move Back' button.
The most common step to move the invoice to is 'Straighten Image'. From here, the invoice is moved back into the recognition process.
Simply select the 'Straighten Image' option, enter a reason and press 'OK'.
This is useful in case of an error message or when testing a template on a set of invoices from a specific creditor.
