Automating the invoice validation and approval process - reporting

Summary:

We are in the process of scheduling the Validate Payables Invoices and Initiate Invoice Approval Workflow for some of our business.

Content (please ensure you mask any confidential information):

The business would like reports of what got processed by these jobs but it does not appear that they produce any reporting. Is there any reporting that can be run, created etc. that would show what invoices are selected and processed successfully by these scheduled processes?
