Urgent: RFC Lookup for BAPI in XI

Question

Hi,
I am trying to call a BAPI that exists in XI system,in the Message Mapping in same XI system.
If I run the BAPI,it is working fine.
But if I call this in XI Message Mapping using RFC lookup,it returns garbage.
I am not getting any RFC error.
Can anyone please tell me what could be the reason for this.
Thanks.
Best Regards,
Shweta

Hi Shwetha,
Please refer the below weblog:
• RFC lookup using JCO (without communication channel)
/people/sravya.talanki2/blog/2005/12/21/use-this-crazy-piece-for-any-rfc-mapping-lookups
• RFC lookup with communication channel.
/people/alessandro.guarneri/blog/2006/03/27/sap-xi-lookup-api-the-killer
Sample code:
public void createAlert(String InterfaceID, String AlertCategory, String errorString,String RFCReceiverCommunicationChannel,String BusinessService)
try{
final String SAPRFCNS = "urn:sap-com:document:sap:rfc:functions",
FUNCTION_MODULE= "Z_FI_RAISE_ALERT";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
factory.setNamespaceAware(false);
factory.setValidating(false);
try {
builder = factory.newDocumentBuilder();
} catch (Exception e) {
Document docReq =null;
try {
docReq = builder.newDocument();
Node root = docReq.appendChild(docReq.createElementNS(SAPRFCNS, FUNCTION_MODULE));
// Creates XML structure which is passed to ABAP function module
root.appendChild(docReq.createElement("I_INTERFACE_ID")).appendChild(docReq.createTextNode(InterfaceID));
root.appendChild(docReq.createElement("I_ERROR")).appendChild(docReq.createTextNode(errorString));
root.appendChild(docReq.createElement("I_ALERTCAT")).appendChild(docReq.createTextNode(AlertCategory));
} catch (Exception e) {
// XML Payload
Payload result1 = null;
try {
Channel channel = LookupService.getChannel(BusinessService, RFCReceiverCommunicationChannel);
RfcAccessor accessor = LookupService.getRfcAccessor(channel);
InputStream is = new ByteArrayInputStream(docReq.toString().getBytes());
XmlPayload payload = LookupService.getXmlPayload(is);
result1 = accessor.call(payload);
} catch (LookupException e) {
// trace.addWarning("Error during lookup - " + e);
// System.out.println(e.toString());
catch(Exception e)
// System.out.println(e.toString());
Thnx
