UDF disappears

Question

Hi,
I have to name the target file dynamically but  i don want the filename to come in the file. SO i am trying to use an UDF with the following code
   //write your code here
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
conf.put(key,a);
I am mapping the filename from the source structure to this UDF. But when i save the message mapping the UDF disappears and am getting this error in the communication channel
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: The Adapter Message Property 'FileName' was configured as mandatory element, but was not supplied in the XI Message header: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: The Adapter Message Property 'FileName' was configured as mandatory element, but was not supplied in the XI Message header
Please help with this.
Regards,
Sharadha

hi,
  In the sender communication channel enable the set adapter specific message attributes
  (Its apper under  Adapter-Specific Message Attributes).You will get the file name dynamically.
