User define Function at Mapping Time

Question

Hello Everyone,
My requirement is I input the one value to the user define function (at mapping time). That function calls the RFC to R/3 system and return the 3 output values. Now my question is how can I return 3-output value from the user define function.
What is the other possibility to solve this type of problem?
Where we have one input parameter and more than one output parameter.
If any one did this kind of job. Please give me the idea how can I solve this.

Hello Richard,
Are you talking about <b>copy head to line</b> example given in MappingFunctionality.pdf.
In my scenario:
Input - NULL
Output - OP1, OP2, RESULT
And I write my Advance user define function as
import com.sap.mw.jco.*;
public void Lookupfunction(ResultList result, Container container){
JCO.Repository mRepository;
// Change the logon information to your own system/user
JCO.Client mConnection = JCO.createClient(
    "100", // SAP client
    "user", // userid
    "pass", // password
    "EN", // language
    "hostid", // host name
    "00" ); // system number
// connect to SAP
mConnection.connect();
// create repository
mRepository = new JCO.Repository( "SAPLookup", mConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("ZTEST2");
function = ft.getFunction();
mConnection.execute( function );
result.addValue( function.getExportParameterList().getString( "OP1" ) );
result.addValue(function.getExportParameterList().getString( "OP2" ) );
result.addValue(function.getExportParameterList().getString( "RESULT" ) );
mConnection.disconnect();
But it shows me only one field as output in mapping icon.
so as per the mapping document i attach splitbyvalue over that but in the example only one field at the output side where i have three field.
How can i solve the problem?
Even i check in XI 2.0 System it doesn't show output at all.
Thanks & Regards,
