It's not uncommon to use your own vehicle for business purposes. Through SAP Concur, you can track any mileage in your personal vehicle that you used for business purposes. You need to know the distance you drove and SAP Concur will calculate the correct reimbursement amount for the distance you drove. You can add this data to your expense report and your reimbursement is on the way.
When you use your personal car for business purposes, you need to create a personal car expense to determine the amount of reimbursement. Your company determines the name of the personal car expense type, usually Personal Car Mileage or something similar. Your company also determines the mileage reimbursement rate.
