Payables Invoice Auditing

I created one new payables invoice then I tried to check it was not visible in Audit reports.

Need to know how to add the attributes in configuration in objects to see the user who deleted, cancelled of the invoice in Audit reports, please provide the path.

I followed all the steps provide in the Document but still the audit report is not capturing the data in Audit Reports, what was the reason??
