How to handle exceptions in sender ABAP Proxy

Question

Hi Experts,
   I have a synchronous scenario.
   SAP R/3 System A -ABAP Proxy <-> PI <-----> SOAP< ---> Webservice
   In system 'A', a function module calls the ABAP Proxy method.
   My requirement is that if there is an exception in PI ( for example: timeout or ABAP engine error) then I want to get the exception details in the calling function module.
For example:
Exception in PI:
  <SAP:Error xmlns:SAP="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.engine.interfaces.messaging.api.exception.MessagingException: java.net.ConnectException: Connection timed out: connect</SAP:AdditionalText>
<SAP:ApplicationFaultMessage namespace=""/>
<SAP:Stack/>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
In the calling function module:
Try
Call to proxy-> method
Catch cx_ai_system_fault INTO v_o_fault.
       v_err_msg1 = v_o_fault->GET_TEXT( ).
       v_err_msg2 = v_o_fault->errortext.
       v_err_msg3 = v_o_fault->code.
Endtry.
Here I get value "MESSAGE.GENERAL" for  v_err_msg1 and v_err_msg3. v_err_msg2 is blank.
I want to capture the info available under <SAP:AdditionalText>. How to get that?
Please help!
Thanks & Regards
Gopal

Hi Gopal,
Maybe the exception is CX_SY_APPLICATION_FAULT, or you can catch by BPM in PI and send back to proxy like a message response.
