Payload

<?xml version="1.0" encoding="UTF-8"?>
<expense-report>
  <payment>
    <notes>Test</notes>
    <payment-date type="dateTime">2016-09-17T00:00:00-04:00</payment-date>
  </payment>
</expense-report>

Note that the Coupa Best Practice is to store the Coupa Expense Report ID in the ERP Connector/ERP, so the Expense Payment can be made directly without querying Coupa for the Expense Report ID. If not saved in the ERP Connector/ERP, and additional step is required to API GET the Expense Report ID.
