.dat to .txt using ASMA

Question

Hi all,
    I am using Adapter Specific Message Attributes(ASMA) to pick a file and place in another folder.
No Mapping is involved.In Communication channel no File content conversion is used.
The sent file is a .dat extension ,and i want the file with filename same at sender and receiver but with a .txt extension.
So,at sender XXXX.dat
     at receiver XXXX.txt
  How can i achieve this?
Thanks in Advance,

hi all,
    i tried using UDF with Dynamic Configuration. But getting an error in Message mapping.
AS this is a dummy mapping , i created the following objects in IR:
Data type: File
Message type: File
Message Interface: mi__o_a  & mi_i_a
Message Mapping: File_MM
Created a UDF and assigned the UDF to the target structure i.e.,
   UDF->File
Interface Mapping: assigned File_MM
Created ID objects also.
And in Sender CC, selected ASMA,
In receiver CC selected ASMA and given the File Name Scheme as *
But still, getting an error in Message mapping,my code in UDF
DynamicConfiguration conf =
(DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File", "FileName");
String file = conf.get(key);     --> i will get the filename as XXXX only ,with no extension such as .dat
String newfile = file+".txt";
    conf.put(key, newfile);
return "";
Where am i wrong,
Please suggest
Thanks
