XML Replay
From DataFlex Wiki
Replaying Logged XML
When attempting to diagnose problems which occur within web service environments, it is often useful to be able to re-run the XML which triggered the problem, so as to be able to step through it in the Visual DataFlex Studio debugger. The XML passed to a web service can be logged (see [XML logging] for details of how this can be done) and this historic data can then be used to "replay" the offending call and see what happened.
