Is there an easier way to change the name of a document node during run time besides converting the document to an XML string and doing a string replace?
Map command to read then drop command. How you need to do this will depend upon if a document type is being used and that type does not define the read field.
Instead of mapping, create a Java service that accepts the document, the source and target names and then use IDataUtil methods to get the command value, remove the command field and then put the read field/value.
