Sending back fault message from receiver to the sender

Question

Hi,
Can somebody explain me, how to capture fault message generated by the receiver system back to the sender system?
I have a synchronous scenario, RFC -> XI -> Web Service.
When web service returns successful response, it gets mapped properly to an internal table of RFC. But, when web service returns fault message (as parameters passed to the web service are incorrect), RFC gives dump. Below message is shown in sxmb_moni.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <!--  Call Adapter
  -->
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
  <SAP:Category>XIAdapter</SAP:Category>
  <SAP:Code area="PARSING">ADAPTER.SOAP_EXCEPTION</SAP:Code>
  <SAP:P1 />
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText>soap fault: com.ucas.hei.link.exception.WSException: Data access error: Incorrect userId/password. at com.ucas.hei.link.xml.ReferenceData.getRefInstUcas(ReferenceData.java:2338)</SAP:AdditionalText>
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack />
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
Has anybody worked with this type of scenario? Please help me.
Thanks & Regards,

Hi Smitha,
if you are calling a webserive from XI and the websevice call results in a soap exception, as of SP13 i am sure there is no way to capture this exception.
Work around approach would be to define exceptions for your sender RFC and hence when an exception is raised in XI, sender RFC will not dump instead you would have the defined exception caught.
CALL FUNCTION 'XYZ'
     EXPORTING
     IMPORTING
     EXCEPTIONS
       OTHERS          = 1.
