In some cases you may have been reimbursed by your company for an expense that you eventually cancelled and for which you received a full or partial refund from the supplier.
For example, suppose that you paid admission fees during the registration process for a conference, but you later cancelled your booking and received a refund from the conference organizer.
Expense provides three ways to report such a case. You can:
cancel the original expense - see Cancelling the Expense from the Original Expense Report
add the refund to a credit card statement in your Expenses Wallet - see Adding the Refund to a Credit Card Statement
add the refund in a new or unsubmitted expense report - see Adding the Refund in an Expense Report
