VO Extension not working in R12

Question

Hi all i have to extend a subtablayout region to add new column ; for that i extended VO which is EO based.
I have done all necessary steps but my problem is this error:
Message not found. Application: FND, Message Name: FND_VIEWOBJECT_NOT_FOUND. Tokens: VONAME = PaymentTransactionsVO; APPLICATION_MODULE = oracle.apps.ce.bankaccounttransfer.server.BankAccountTransferAM;
i cannot find the new field on page & its not recognising the VO & i am stuck..
My approach is to change the query as the original query doesnt hav the required attr but i didnt change query in expert mode because expert mode option is disabled for my VO . I dontknw if i have done right or wrong.
Any guidance will be gr8888888888 helpppppp for meeee...
Thanks,

AJ,
Fine for New field ExchangeRateValue i thought same but for executing the query in both cases after binding with run time param..
I need to setwhereclauseparam right?????
can u plz give me any code snippet to make me clear as SOB_id is not given on run time it shud be selectd automatically according to Bank Legal entity but yess for currency LOV i can fetch from LOV selection i chnged my code like this:
if("currency".equals(lovInputSourceId))
OAMessageLovInputBean lovCurrencyBean=(OAMessageLovInputBean)webBean.findChildRecursive("currency");
pageContext.writeDiagnostics(this,"LOV Bean is "+ lovBean + "...",OAFwkConstants.STATEMENT);
lovInput = null;
if(lovCurrencyBean != null)
if("lovValidate".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)) || "lovUpdate".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
System.out.println("IN IF");
lovInput= pageContext.getParameter("currency");
if ("USD".equals(lovInput))
try {
Connection conn = pageContext.getApplicationModule(webBean).getOADBTransaction().getJdbcConnection();
String Query = "SELECT PaymentTransactionsEO.TRXN_REFERENCE_NUMBER,PaymentTransactionsEO.Transaction_Date,PaymentTransactionsEO.Payment_Currency_Code,GLDR.Conversion_Date,csp.cashflow_exchange_rate_type,gl.user_conversion_type exchange_rate_type, GLDR.CONVERSION_RATE exchange_rate_value FROM CE_PAYMENT_TRANSACTIONS PaymentTransactionsEO, CE_SYSTEM_PARAMETERS CSP, GL_SETS_OF_BOOKS SOB, gl_daily_conversion_types GL, gl_daily_rates GLDR where SOB.SET_OF_BOOKS_ID = CSP.SET_OF_BOOKS_ID AND csp.CASHFLOW_EXCHANGE_RATE_TYPE = GL.Conversion_Type and GL.Conversion_Type=GLDR.CONVERSION_TYPE and GLDR.Conversion_Date=PaymentTransactionsEO.Transaction_Date and gldr.from_currency=PaymentTransactionsEO.Payment_Currency_Code and CSP.LEGAL_ENTITY_ID is not null AND and csp.set_of_books_id = 2063 and PaymentTransactionsEO.Payment_Currency_Code=:1 ";
PreparedStatement stmt = conn.prepareStatement(Query);
for(ResultSet resultset = stmt.executeQuery(); resultset.next();)
pageContext.writeDiagnostics(this, "Query Executed", OAFwkConstants.STATEMENT);
String result1 = resultset.getString("exchange_rate_value") ;
pageContext.writeDiagnostics(this, "Query for ExchangeRateValue Executed " + result1,OAFwkConstants.STATEMENT);
OAMessageStyledTextBean ExchangeRateValueBean = (OAMessageStyledTextBean)webBean.findChildRecursive("ExchangeRateValue");
ExchangeRateValueBean.setValue(pageContext,result1);
catch(Exception exception)
throw new OAException("Error in Query"+exception, OAException.ERROR);
please suggest..
Thanks
