Invoice Aprpoval Workflow -

R12:How To Know Which User Is Linked To 'Accounts Payable' In Invoice Notification Approval Workflow ( Doc ID 2145570.1 )

I got confused by the above KB doc., can any know exactly the design of the workflow?

In the application Worklist approval process when user select Request Information it can either request more information from Workflow Participant - Accounts Payable or Any user

But in the email notification there is no such selection for the approver it can only goes to AP_ACCOUNTS_PAYABLE

Scenario

Employee A -Who create and submit the invoice from the Invoice Workbench / Or she's the person who execute the Autoinvoice request process
