Dynamic File and Directory Name without Mapping

Question

Hello Experts,
We have following requirement:
1) Files will be picked from R/3 AL11 directory and would be placed in corresponding folder in target system.
2) On source side ,there would be only one folder for all types of files(around 20),but on target side,there would be one folder for each kind of file(20 folders)
3) File name should be same on the target side but target directory should be selected based on file name.
I have gone through a number of posts related to similar requirements and hence,sorry for a new post but I am not yet able to find a solution to this.
I could understand,this can be achieved using DynamicConfiguration UDF .
But I have no possibility to have mapping in my scenario.It would just be a pass through scenario.
Can anyone please suggest a solution to this?
Thanks.

Hello,
Thanks a lot for suggesting solution to this problem.
I could achieve this using following Java mapping:
import com.sap.aii.mapping.api.*;
import java.io.*;
import java.text.*;
import java.util.*;
public class GetDynamicConfiguration implements StreamTransformation {
    private Map param;
    public void setParameter(Map map1) {
        this.param = map1;
    public void execute(InputStream inputstream, OutputStream outputstream) throws StreamTransformationException {
        try {
               AbstractTrace  trace = null;
            // a) Set ouput File name
            String directory=null;
               trace = (AbstractTrace)param.get(StreamTransformationConstants.MAPPING_TRACE );
            param.put(DynamicConfigurationKey.create("http://sap.com/xi/XI/Dynamic", StreamTransformationConstants.DYNAMIC_CONFIGURATION), "");
            DynamicConfiguration conf = (DynamicConfiguration) param.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
            DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
               DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "Directory");
            String filename =conf.get(key);
            conf.put(key, filename);
               trace.addInfo("File name is "+filename);
            if(filename.equals("in.txt"))
            directory = "/home/ftpxi/in";
               if(filename.equals("test.txt"))
               directory = "/home/ftpxi/in/test";
               if(filename.equals("shweta27.txt"))
               directory = "/home/ftpxi/in/test";
               trace.addInfo("Directory name is "+directory);
               conf.put(key1, directory);
            // b) Just copy input file to output file
            byte[] b = new byte[inputstream.available()];
            inputstream.read(b);
            outputstream.write(b);
        } catch (Exception exception) {
            exception.printStackTrace();
Thanks again.
