To RECEIVE an EDI file, you need a receive pipeline with an EDI disassembler.
The EdiReceive pipeline in the EDI BizTalk application is what you are looking for most likely. By default this pipeline does the necessary tracking, so you should be able to see in the "Tracked Message Events".
You should always try to do it step by step:
EdiReceive disassemble to XML file and subscribe to that file using a send port.
Once this works, try mapping the result with a 'Test Map' using VS. You might notice you did something wrong there.
Once this works, deploy your mapping to BizTalk and set it in the send port as an outbound map, so it gets executed.
Hope this helps.
