Rename Filename using FTP adapter

Question

Hi All,
I have a simple file to file scenario with renaming the filename of the file at the target.
Source Filename - ABC
Target Filename (Expected) - ABC_pqr
I am using adapter specific message attributes to generate filename as '%filename%_pqr' as target filename, but only the filename 'ABC' appears in the target filename and additional '_pqr' is neglected.
Is there a way by which this can be achieved? I know, there is a option of using OS Command to rename the file at source and than use the filename.
Are there any other options, by which it can be achieved?
Thanks for your help in advance.
Regards,
Ashish

Hi Ashish,
Use Dynamic configuration. Here is the Code: Map to the target root node.
public String Filename(String a,Container container)
  String b;                                                 // Target file Name
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey keyHeader1 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
b =  /* Here the condition to rename the file
conf.put(keyHeader1, b);
return "";
Thanks,
