Credit Card Transactions for Termed employee with submitted expense report

Hello Everyone,

Oracle has provided a program "Credit Card Transactions Inactive Employees Process" to assigned outstanding credit card transactions to supervisor of termed employee so that he can file expense report on behalf of him. However we have a scenario where termed employee before the terminated submitted the expense report. When this expense report was under approval process, we terminated the employee. In this particular scenario how can we de-link these outstanding credit charges so that we can utilize  "Credit Card Transactions Inactive Employees Process"

Please let me know if anyone has experienced the same problem and have any solution available.
