Call Adapter Error

Question

Hello everybody,
I have a synchronous scenario ABAP Proxy->XI->RFC, the reason why we used XI it's beacuse by company politics any systems integration needs to go by SAP XI, and the reason why we used RFC in the receiver system it's because by company politics too we can't generate proxies in that system, so we decided to go by RFC, now the interface is working really fine, the abap proxy in the sender system is called by a Z program, so this program gives a report of every record, and the problem that I'm facing is that I need to give back to the sender systems errors like this:
<?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>XIAdapterFramework</SAP:Category>
  <SAP:Code area="MESSAGE">GENERAL</SAP:Code>
  <SAP:P1 />
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText>com.sap.aii.af.ra.ms.api.DeliveryException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not convert request from XML to RFC:com.sap.mw.jco.JCO$ConversionException: (122) JCO_ERROR_CONVERSION: Date '9999-12-32' has a wrong format at field VALIDA: Unparseable date: "9999-12-32"</SAP:AdditionalText>
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack />
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
this error it's beacuse of the day 32 of the month december, we know that, but this error is only treated as exception CX_AI_SYSTEM_FAULT in the Proxy, and I need to pass the SAPAdditionalText of the error above to the sender system, is there a way to give back to the proxy this text so it will be more explicit in the error and not just a SYSTEM_FAULT???????, thanks in advance.

Hello VJ,
Thanks for your answer, about the solution your are kindly giving me, it's not really clear to me in this point:
" When ever you get such exceptions, you need to catch them
in your RFC and fill your own exception object and throw it."
the exception I'm getting is a default by SAP, not one I could raise, maybe I'm not understanding right your proposal could you explain me more this part, do you mean that if I declare an exception in my RFC even if I'm not doing the RAISE is going to catch the exception I'm getting?, thanks a lot for your answer.
