Reg. RFC look up

Question

Hi All,
I am working on RFC look up. My Scenario is IDoc to IDoc. The IDoc has a segment say E1 where the occurence is 0---5 and two fields inside that i.e. QUALF and IDTNR.  The requiremnt is like when QUALF  is equal to 002 then fetch the value of material number from SAP and map to IDTNR. Also this material number is picked only when QUALF is equal to 003 and the field IDTNR has some value i.e. article number in SAP. So I need to get value of the material number equal to this article number.
I am using RFC look up for this mapping condition in order to fetch value from SAP.
Can anyone help me on this to configure the RFC look up in PI?
Thanks and Regards,

Hi All,
For my requirement I have used this UDF,
String content = "";
MappingTrace importanttrace;
importanttrace = container.getTrace();
// filling the string with our RFC-XML (with values)
String m ="<?xml version=\"1.0\" encoding=\"UTF-8\"?><ns0:ZSD_EAN_MATERIAL_GET xmlns:ns0=\"urn:sap-com:document:sap:rfc:functions\"><P_EAN11></P_EAN11></ns0:ZSD_EAN_MATERIAL_GET>" ;
RfcAccessor accessor = null;
ByteArrayOutputStream out = null;
try
// 1. Determine a channel (Business system, Communication channel)
Channel channel = LookupService.getChannel("RD9","CC_RFC_RECEIVER_LOOKUP_I040");
// 2. Get a RFC accessor for a channel.
accessor = LookupService.getRfcAccessor(channel);
// 3. Create a xml input stream representing the function module request message.
InputStream inputStream = new ByteArrayInputStream(m.getBytes());
// 4. Create xml payload
XmlPayload payload = LookupService.getXmlPayload(inputStream);
// 5. Execute lookup.
Payload result = accessor.call(payload);
InputStream in = result.getContent();
out = new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
for (int read = in.read(buffer); read > 0; read = in.read(buffer)) {
out.write(buffer, 0, read);
content = out.toString();
catch(LookupException e)
importanttrace.addWarning("Error while lookup " + e.getMessage() );
catch(IOException e)
importanttrace.addWarning("Error " + e.getMessage() );
finally
if (out!=null) {
try {
out.close();
} catch (IOException e) {
importanttrace.addWarning("Error while closing stream " + e.getMessage() );
// 7. close the accessor in order to free resources.
if (accessor!=null) {
try {
accessor.close();
} catch (LookupException e) {
importanttrace.addWarning("Error while closing accessor " + e.getMessage() );
//returning the result u2013 RFC-XML.response
return content;
While executing this UDF I am getting the output as:
<?xml version="1.0" encoding="UTF-8"?><rfc:ZSD_EAN_MATERIAL_GET.Response xmlns:rfc="urn:sap-com:document:sap:rfc:functions"><Materialnumber></Materialnumber></rfc:ZSD_EAN_MATERIAL_GET.Response></IDTNR>
  <KTEXT />
instead of value
Can anyone suggest me on this?
