Deleting or omitting Special characters in PI mapping

Question

Hello ,
    My scenario is , SAP ECC to legacy , ie. IDOC --> XI/PI -BPM --> Legacy(XML) ,
  here in Idoc we have a field which gives has a special character '§'  which I need to remove this before it goes out from PI.
how to handle this , Is there a best way to do?
  Note : From legacy they can handle other character but legacy system could not accept this char.
Regards,
Sethu.

Hi Sethu,
                 here is the java mapping code to meet your requirement. I assumed you are working on PI 7.1 or above versions.
The java mapping code pattern,associated library files and compilation enviornment are different in PI7.0 and lower versions.
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Map;
import com.sap.aii.mapping.api.AbstractTransformation;
import com.sap.aii.mapping.api.StreamTransformationException;
import com.sap.aii.mapping.api.TransformationInput;
import com.sap.aii.mapping.api.TransformationOutput;
public class RemoveSpecialChar extends AbstractTransformation {
      * @param args
     public void execute(InputStream in, OutputStream out)
               throws StreamTransformationException {
          // TODO Auto-generated method stub
          try
               byte b[]=new byte[in.available()];
               String encoding="UTF-8";
               in.read(b);
               String inputXML=new String(b);
               inputXML=inputXML.replaceAll("§","");
               out.write(inputXML.getBytes(encoding));
          catch(Exception e)
               throw new StreamTransformationException(e.getCause().toString());
     public void setParameter(Map arg0) {
          // TODO Auto-generated method stub
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          try{
               RemoveSpecialChar genFormat=new RemoveSpecialChar();
               FileInputStream in=new FileInputStream("C:\Apps\my folder\sdn\qmark.xml");
               FileOutputStream out=new FileOutputStream("C:\Apps\my folder\sdn\qmark1.xml");
               genFormat.execute(in,out);
               catch(Exception e)
               e.printStackTrace();
     public void transform(TransformationInput arg0, TransformationOutput arg1)
               throws StreamTransformationException {
      this.execute(arg0.getInputPayload().getInputStream(), arg1.getOutputPayload().getOutputStream());
you need to use this mapping before message goes out of PI server.
