Show fields from sales order in xml file using dynamics ax 2012

Hi,

I am currently using Dynamics AX 2012 R3. I need to show two fields i.e. Barcode and ExternalItemId from the sales order in the already existing xml file.

The two fields are present AR>All sales order. If you open any sales order under the load details you will get the fields (barcode and externalitemid).

Also, I have enabled them from the outbound port in the ax, but still I cannot get the fields come on the xml file. Please suggest
