Renaming the file from in a static way.

Question

Hello  everyone,
Its a Mail to File scenario. There is no mapping involved in this scenario.
There  is a XLS file coming as an attachment  and this needs to be dropped in FTP server.
But there are 7 reports and i want to use only one communication channel.
So if the File name is A then it has to be renamed as B. If the file name is C then it has to be renamed as D.and so on ...
How to achieve this. ?
Regards,
Ravi

You can use Java mapping to do that, use this mapping program in Operation mapping in your ID interface determination. Here is a sample code of it, You can use case statement to put your conditions.
public class RenameFile extends AbstractTransformation  {
      private static final DynamicConfigurationKey KEY_FILENAME =
      DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
       public void transform(TransformationInput in, TransformationOutput out)
       throws StreamTransformationException {
                 String newFileName = null;
               Date date = new Date(); // get the current date
               SimpleDateFormat dateFormatter = new SimpleDateFormat ("yyyyMMddHHmmss"); // set the format for date
               String dfmt =  dateFormatter.format(date);
               DynamicConfiguration conf = in.getDynamicConfiguration();
                String oldFileName = conf.get(KEY_FILENAME);                    // filename is <store_ID>.txt
                newFileName = dfmt + oldFileName; // Final file will have date in file name
                String inData = convertStreamToString(in.getInputPayload().getInputStream());
                String outData = inData;
                try {
                    out.getOutputPayload().getOutputStream().write(outData.getBytes("UTF-8"));
               } catch (UnsupportedEncodingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
               } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
               conf.put(KEY_FILENAME,newFileName);
       public String convertStreamToString(InputStream in){
               StringBuffer sb = new StringBuffer();
               try
               InputStreamReader isr = new InputStreamReader(in);
               Reader reader =
               new BufferedReader(isr);
               int ch;
               while((ch = in.read()) > -1) {
                    sb.append((char)ch);}
                    reader.close();
               catch(Exception exception) { }
               return sb.toString();
