DynamicConfigurationException:Unable to set ASMA in Module

Question

Hi,
I have written customized adaptor module and trying to set the FileName to Dynamic Configuration object. But it is throwing error.
I used the below code:
Message msg = null;
MessagePropertyKey key= new MessagePropertyKey("http://sap.com/xi/XI/System/File","FileName");
msg.setMessageProperty(key,"Testing");
moduledata.setPrincipleParameter(msg);
I have enabled "FileName" the ASMA(adapter specific message attribute) in receiver communication channel. But it is throwing the below exception.
"DynamicConfigurationException:: The adapter message property "FileName" was specified as mandatory element, but was not supplied in XIMessageHeader".
Working on PI7.1.
Please let me know, if i need to do any changes.

"DynamicConfigurationException:: The adapter message property "FileName" was specified as mandatory element, but was not supplied in XIMessageHeader".
I used the below code:
Message msg = null;
MessagePropertyKey key= new MessagePropertyKey("http://sap.com/xi/XI/System/File","FileName");
msg.setMessageProperty(key,"Testing");
moduledata.setPrincipleParameter(msg);
just you have to use below code insted of what ever u wrote the code.
String DynamicConfig(String a, Container container) throws StreamTransformationException{
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);
return "";
and in Receiver file communication channel , just you have to enable ASMA and file name.
Note:
if Ur scenario is File To File then just enable Asma and file name in both sender and receiver adapters.
