It is possible that some of your Invoices were approved for payment directly in NetSuite and, therefore, bypassed the approval workflow.
This is how you build a report to track such cases
First, activate the setting in your approval workflow
Select your Organisation in the main menu and go to Approval workflows under Workflows and settings:
Open the Invoice workflow and click on the Gear icon. Then activate the FRAUD DETECTION - BYPASSING THE APPROVAL WORKFLOW setting:
This will allow ApprovalMax to pull all requests that were approved directly in NetSuite.
Update the approval workflow to save your changes.
Next, set up a report
Select your Organisation in the main menu and go to Request Reports under Reports.
Click on the NEW REPORT button:
Activate the checkbox next to Invoice and click on NEXT:
Apply the filter "Fraud risk - Resolved directly in NetSuite" and click on NEXT:
Select the columns you want to see in the report and click on NEXT.
Finally, name your report and click on CREATE:
