Problem to analyse mapping error

Question

Hi all,
I have a problem to analyse a BPM mapping error on PI7.1. The szenario is as follows: I have 3 different containers (Abstract Interfaces) which data is used to determine the content of a  result container.
E.g:
ABSTRACT_INTERFACE_1
ABSTRACT_INTERFACE_2 -> Mapping -> ABSTRACT_RESULT_INTERFACE
ABSTRACT_INTERFACE_3
If have quouted the source interfaces (cardinality 1 for each interface)  in my operation mapping and configured the transformation step accordingly. The operation mapping alone works in the integration builder test environment. When I execute the BPM process, the mapping fails. Unfortunately the is no information in the trace leaf of the respective container information. Writing data to the mapping trace doesn't work neither.
Has got anybody an idea what might be the problem?
Kind regards,
Heiko

Hi Heiko,
Pls, do the following:
1. Build a java mapping which is going to write the payload content before the message mapping.
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.StreamTransformationException;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Map;
public class InputFileWriter implements StreamTransformation {
    public void setParameter(Map map) {
    public void execute(InputStream in, OutputStream out)
    throws StreamTransformationException {
        try{
            File f=new File("C:\PayloadContent.xml");
            FileOutputStream fosPayload = new FileOutputStream(f);
            byte[] content= new byte[in.available()];
            int c;
            int i=0;
            String sb =  "";
            while ((c = in.read()) != -1){
                content<i>=(byte)c;
                sb += (char)content<i>;
                i++;
            fosPayload.write(sb.getBytes());
            fosPayload.close();
            out.write(sb.getBytes());
            out.close();
        }catch(Exception ex){
            ex.printStackTrace();
2. Add the javamapping to your interface mapping putting before of message mapping.
3. Run your scenario.
4. Check the file
C:\PayloadContent.xml
5. Test your message mapping in with PayloadContent.xml
And tell me what happened.
Regards
Ivan
