How to Release Credit Card Transactions in AP by loading Expense report from 3rd party( Not Oracle iExpenses)

Here is the scenario

1. We are on Corporate pay credit card setup

2. The credit card invoice ( Credit Card provider) is paid out of Oracle Payables- DR; Clearing Account/CR :Cash

3. The credit card file is loaded into a 3rd party application e.g. concur and a flat file is generated from Concur to be loaded in to Oracle AP as Expense Invoice to offset the Clearing account in AP

4. How can we do this such that when the expense invoice details are loaded into AP, they offset the Clearing account e.g. DR:Expense & Credit Clearing account.
