UDF For Retrieving the Tax Code based on PO

Question

Hi all,
Mine is a file to Idoc scenario.
I wrote a FM to retrieve the Tax Code based on PO .
Created the udf which directly gets the Taxcode from the r/3 with out importing in to the imported objects,is this correct i never tried this before.
Find the UDF for the Same.
final String    CHANNEL_NAME = "GeneratedReceiverChannel_RFC",
     VALNOTFOUND = "VALUE_NOT_FOUND",
     SAPRFCNS = "urn:sap-com:document:sap:rfc:functions",
     TAG_FM = "Z_P_INT012_RFC_LOOKUP",
     TAG_TAX_CODE = "T_TAX_CODE",
     TAG_TAX_CODE_P = "TAX_CODE";
AbstractTrace trace = container.getTrace();
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          DocumentBuilder builder = null;
          factory.setNamespaceAware(false);
          factory.setValidating(false);
          try {
               builder = factory.newDocumentBuilder();
          } catch (Exception e) {
               trace.addWarning("Error creating DocumentBuilder - " + e.getMessage());
          Document docReq = null;
          try {
               // Building up RFC Request Document
               docReq = builder.newDocument();
               Node root = docReq.appendChild(docReq.createElementNS(SAPRFCNS, TAG_FM));
               Node nodeTbOpt = root.appendChild(docReq.createElement(TAG_TAX_CODE));
               for (int i = 0; i < pernr.length; i++) {
                    Node nodeTbOptItem = nodeTbOpt.appendChild(docReq.createElement("item"));
                    nodeTbOptItem.appendChild(docReq.createElement(TAG_TAX_CODE_P)).appendChild(docReq.createTextNode(TAX_CODE<i>));
          } catch (Exception e) {
               trace.addWarning("Error while building RFC Request  - " + e);
          trace.addInfo("RFC Request XML: " + docReq.toString());
                                                //trace.addWarning("RFC Request XML: " + docReq.toString());
          // Lookup
          Payload load = null;
          try {
               Channel channel = LookupService.getChannel(receiver[0], CHANNEL_NAME);
               RfcAccessor accessor = LookupService.getRfcAccessor(channel);
               InputStream is = new ByteArrayInputStream(docReq.toString().getBytes());
               XmlPayload payload = LookupService.getXmlPayload(is);
               load = accessor.call(payload);
          } catch (LookupException e) {
               trace.addWarning("Error during lookup - " + e);
          // Parsing RFC Response Document
          Document docRsp = null;
          try {
               docRsp = builder.parse(load.getContent());
          } catch (Exception e) {
               trace.addWarning("Error when parsing RFC Response - " + e.getMessage());
          trace.addInfo("RFC Response XML: " + docRsp.toString());
                                                //trace.addWarning("RFC Response XML: " + docRsp.toString());
          try {
               NodeList res = docRsp.getElementsByTagName("item");
               for(int i=0;i<res.getLength();i++){
                    NodeList itemNodes = res.item(i).getChildNodes();
                    Map itemMap = new HashMap();
                    for(int j=0;j<itemNodes.getLength();j++){
                         itemMap.put(itemNodes.item(j).getNodeName(), itemNodes.item(j).getFirstChild().getNodeValue());
                    rows.add(itemMap);
                                                        catch (Exception e) {

Hi Potharaju,
Why don't you try this, that really works:
If you are using PI 7.1:
http://help.sap.com/saphelp_nwpi71/helpdata/en/33/1ec6ced273493a993a80c2301c03da/frameset.htm
If you are using XI 3.0, PI 7.0
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a03e7b02-eea4-2910-089f-8214c6d1b439
Try with these.
