Calling RFC using UDF

Question

Hi,
I have a small doubt.
In file to IDOC mapping, I am mapping two fields using a UDF.
That UDF in turn calls a RFC.
But that RFC is not moved to quality server.
If now I try to test that in quality environment, the mapping works fine and IDOC is posted because the error handling is done in ABAP.
My doubt is why did the messge did not failed in XI, saying the RFC not available??
I tried to search in sdn, by did not get anything related to this.
Please try to clarify my doubt.
Regards,
Sachi

Ravi,
Below is the UDF code:
MappingTrace importantTrace = container.getTrace();
String query = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><ns0:Z_RFC_UOM xmlns:ns0=\"urn:sap-com:document:sap:rfc:functions\">";

String Lookup_Key_Tag = "I_MATNR";
String Lookup_Key_Tag1 = "I_VKORG";

String Lookup_Value_Tag = "E_MENEE";
String Lookup_key_StartTag = "<" + Lookup_Key_Tag + ">";
String Lookup_key_EndTag =  "</" +Lookup_Key_Tag + ">";
String Lookup_key_StartTag1 = "<" + Lookup_Key_Tag1 + ">";
String Lookup_key_EndTag1 =  "</" +Lookup_Key_Tag1 + ">";
String Lookup_key_StartTag2 = "<" + Lookup_Key_Tag2 + ">";

            ItemsTag =  Lookup_key_StartTag material<i> Lookup_key_EndTag;
            item1 = item1 + ItemsTag;

            ItemsTag =  Lookup_key_StartTag1 sales_org<i> Lookup_key_EndTag1;
            item2 = item2 + ItemsTag;
for(int i= 0;i< dist_channel.length;i++)
            ItemsTag =  Lookup_key_StartTag2 dist_channel<i> Lookup_key_EndTag2;
            item3 = item3+ ItemsTag;

query = query + items;
RfcAccessor accessor = null;

comm_channel = "CC_Recv_RFC";
try
            Channel channel = LookupService.getChannel(Rec,comm_channel);

            content = out.toString();
            importantTrace.addWarning("RFC Response::" + content);

            j= 0;
            while ( content.indexOf(Lookup_Value_StartTag) != -1 )
                                                            Lookup_Value = content.substring( content.indexOf(Lookup_Value_StartTag) + Lookup_Value_StartTag.length()  , content.indexOf(Lookup_Value_EndTag) ) ;
                                                            importantTrace.addWarning("LookupValue::" + Lookup_Value);

}//end of try

            importantTrace.addWarning("Error while lookup"+ ex.getMessage());
//catch(LookupException e){  importantTrace.addWarning("Error while lookup"+ e.getMessage()); }
//catch(IOException e) { importantTrace.addWarning("Error while IOException"+ e.getMessage()); }
finally
            if(out!=null)
                        try
                                    out.close();
                        catch(IOException e)
                                    importantTrace.addWarning("Error while IOException"+ e.getMessage());
            if(accessor!=null)
                        try

                        catch(LookupException e)
                                    importantTrace.addWarning("Error while lookup"+ e.getMessage());
result.addValue("");
