Expense Management Duplicate Checking

Hi Comm

Does anyone know how duplicate payments can be prevented in this scenario: A credit card statement is imported and there is a hotel charge. The reimbursement is to the Credit card company. The employee enters the C card receipt and the reimbursement is to the employee. Is there a system way to prevent this as the duplicate checking in exp mgmt works on the employee entries. Or will it be a manual process

thank you
