(Add message id in configuration should not be done.)

Hello shruthi,
              Please try this for the filename creation,
1. Create a UDF in the message mapping named getFileName, select only one input (to pass the messageid) and paste this coding there;
/* getFileName User Defined  Function
// function to create name of output file
String filename;
filename = strFile;
try {
// initialize DynamicConfiguration for create file with given name
DynamicConfiguration conf = (DynamicConfiguration) container
       .getTransformationParameters()
       .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
//create file with the specified name 
conf.put(key, filename);
} catch (Exception ex) {
return filename;
2. In the target structure header field perform this mapping,
Messageid -> getfFileName UDF -> Target Structure Headerfield
3. Then in the Integration directory under the target tab
check the Use - adapter specific message attributes and File Name
Please follow the steps and let me know if u still face the same problem.
