Dear friends and Oracle experts ,

Due to our company policies, we use two separate expense templates for personal vehicle expenses (mileage) and other employee expenses types.

For other employee expenses kinds of expense reports, an expense report type invoice is created in the AP Module and payments are made with the AP payment functionality.

Personal vehicle expenses types of expense reports are paid on Payroll due to company policies and legal regulations.

For this reason, different expense reports must be created for employee expenses entered for personal vehicle expense (mileage) and other employee expense types.
