XI testing POS Integration Scenario

Hi Folks ,

I am new to XI environment and have a query:

I am configured a process integration scenario for sending TLOG to POSDM. Can you pl advice how can I go about testing my config. At present I do not have any POS-GM system running so I was wondering that I will have to put my *.txn file in the "Source Directory" specified folder...

How can I do a test ..pl advice.

thanks!!
