Table lookup instead of fixed value mapping

Question

Hi Folks,
My current scenario is that I have used fixed value mapping to map a single target field.  These details are actually maintained in the TP_Code table in R3 (a sample table).
TradingPartner:SAP:Short Text
PA:PA:Package
PL:PAL:Pallet
The table contains 20 entries.
I am thinking that fixed value mapping is not a good option since there might have future changes in the TP_Code table.
Is rfc lookup a good option?  But I am not sure which rfc to use and if there is any udf availble to be used in parsing the xml payload.
Please advise.
Thanks a ton!

Thanks so much for the links!
I managed to use and run the RFC lookup to an R3 table using JCo.  However, I am not getting the right result.
I am getting the result in this format -> 800,PA,PAC,Package
The correct output is PAC which is the third node.  Could this only be achieved by using java tokenizer?
The code that I have used is as follows:
Import com.sap.mw.jco.*;
//write your code here
String DBTABLE = a;
String WHERE_CLAUSE = b" = ""'"c"'" ;
String sapClient = "xxx";
String hostName = "nnnxxx";
String systemNumber = "xx";
String userName = "nnnnn";
String password = "******";
String language = "EN";
JCO.Repository mRepository;
JCO.Client mConnection = JCO.createClient(
               sapClient,
               userName,
               password,
               language,
               hostName,
               systemNumber );
// connect to SAP
mConnection.connect();
// create repository
mRepository = new JCO.Repository( "SAPLookup", mConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("RFC_READ_TABLE");
function = ft.getFunction();
// Obtain parameter list for function
JCO.ParameterList input = function.getImportParameterList();
// Pass function parameters
input.setValue( DBTABLE, "QUERY_TABLE");
input.setValue( "," , "DELIMITER");
//Fill the where clause of the table
JCO.ParameterList tabInput = function.getTableParameterList();
JCO.Table inputTable = tabInput.getTable("OPTIONS");
inputTable.appendRow();
inputTable.setValue(WHERE_CLAUSE,"TEXT");
mConnection.execute( function );
JCO.Table valueSet = function.getTableParameterList().getTable("DATA");
String resultSet = valueSet.getString("WA");
mConnection.disconnect();
return resultSet;
