2. Go to the Sales Orders view.
3. Open the order ABC001, in the Output History tab, the Send By is XML. Click View XML you are able to check the detailed output XML. The extension fields are empty there. 
4. However, if you open another sales order ABC002 which exact the same order but sent by E-Mail, the output XML shows the expected extension fields value.
