John,
Thanks a lot for your response.
Still I am in confusion in logging the message into the text file.
Suppose if I receive an XML file from an external to BizTalk, by using the HAT tool we can check whether that message has been logged in or not. if I am converting that XML file to a Flat File then before sending that flat file to external I want to log the message by creating a text file in some folder. Is it possible to create a text file and write the message by using Orchestration?
Please clarify.
