From within the map tool we can attach an xml message and click the play
button without a failure.
If we add the schema's and the map to a process flow we receive the
following error, there are no errors in the process flow list.
DataMapping Failed Error in execution for activity DataMapping:testDataMapping:100000880021
36639925879800058[Error in execution : Premature end of file.]
Using an XML schema before the Data Mapping
Since the XML schema is already contained within the Data Mapping, you can remove the XML Schema activity before the Data Mapping within the Process Flow Designer
