Hi all,
Find the error message I am Getting.
RuntimeException in Message-Mapping transformation: Exception:[java.lang.ArrayIndexOutOfBoundsException: 0] in class com.sap.xi.tf._MM_INT012_INVOICE_DET_ method doRfcLookup$[com.sap.aii.mappingtool.tf3.CBufIter@3ada2bc3, com.sap.aii.mappingtool.tf3.CBufIter@496f2d64, com.sap.aii.mappingtool.tf3.CBufIter@220d25e6].
My Input paramenters:
doRfcLookup(String[] Tax_amt,String[] DTL,String[] Recv_Sys,ResultList result,Container container):
Rfc connection:
Payload load = null;
          try {
               Channel channel = LookupService.getChannel(Recv_Sys[0], CHANNEL_NAME);
               //Channel channel = LookupService.getChannel("ECC", 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);
Quick reply would be appreciated.

Add More trace will get you to know at what step error occured
May be add mappingtrace which providesyouj more info at the mapping test tab
Input should be string if it is value type
