File Adapter - ASMA

Question

Hi,
Scenario:
FTP - XI - FTP
File is retrieved using FTP and does not have extension. Example "abc"
File is to be stored by appending ".txt" to the filename.
So filename on receiver FTP channel should be abc.txt
Source file name is dynamic.
How do I add an extension (.txt) to a dynamic source filename ?
I was thinking abt Variable substitution like %fname%.txt but filename is not passed in the payload, so how do I replace fname ?
Any other ideas ?
Thanks

Hi Aamir,
Ok, I did create message mapping by just mapping the UDF to the target node.
But how do I create IM for this as it does not have any source message type ?
I was hoping to use it in my current IM where I map source MT to receiver MT (which in my case are same message type  (STRING) ). In my current map, I call a ABAP class which I am supposed to use for some other purpose. This is already working.
I then did use it in my current IM as an additional mapping step and ran the interface and failed.
BTW, I am using %FileName%.txt in the file scheme and NOT using any variable substitution in the recvr comm channel.
I get error as:
