File Receiver Adapter : ASMP Question

Question

Hi all,
My requirement says i need to name my target file like this: <XYZ><YYYYMMDDHHMMSS>
Now i knw that i can achive this via the Adapter Specific msg  parameter but don't know how to proceed.
i have done this so far,
After referin this thread:[Receiver File Adapter - TimeStamp;
In the mapping done a UDF:
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String SourceFileName = conf.get(key);
String newfilename=SourceFileNamea; //Where a is a string that holds YYYYMMDDHHMMSS+
// change to new file name
conf.put(key, newfilename);
return "";
i have not done anything else apart from this UDF in the design, nothing in the Configuration, Which is why maybe i am not getting the desired result. My recv channel has this in the file name: XYZ
i get a file in the target directory like this: nullYYYYMMDDHHMMSS Don't knw y i get the null @ the beginning and don't know y it overrides the XYZ in the recv adapter File name tab.

Hi Hankovak,
   Please do the following check list:
1. Map to any of the higher level node it can be top most  message type node (eg.MT_Msg1).So that the modified name will be available  on the target side ASMA.
2Check the syntax again by right clicking on the UDF and selecting QUEUE.
3.In the communication channels of both sender and receiver  check the ASMA check box.
4.in the receiver side communication channel give  * asterik in the receiver file name scheme. uncheck the add timestamp as well .your UDF might be using the time stamp from the communication channel reporting Null value in the file name.This will definitely solve your problem
Please refer the follwing blog on ASMA for more clearifications.
