How to populate custom table field value into standard DFF

Question

Hi Gurus
I am newbie to the OAF
I have a requirement to populate the custom table field value into standard DFF. we enabled the DFF in ReqDistDFFOnAcct(po_req_distributions_all). On the requisition tab as soon as i click on the checkout button, the custom field value has to be shown in the requisition distributions DFF field along with the standard Columns like charge account, percent, qty and when we click on the next button, it has to hit the base table ie., po_req_distributions_all.
the standard columns data is showing the screen. how to acheive this requirement programatically
There is a EO for the req distributions table. please help me how to achevie this requirement.
Any help woud be greatly appreciated.
Thank You!
Krishna

Thanks Aj. Finally i made some progress....but i am getting an error in the inst_top OPMN folder 10/10/08 15:37:14 Error: <connector name="OracleASjms" path="OracleASjms.rar" /> will not be bootstrapped since corresponding module declaration was not found in application.xml. I cleared the cache, bounced the webserver. Could not able to understand what is this error
Following is the code that i have written. I am not able to find out what is the error. please help me how to fix this error. there is no changes in the page and the value is not auto populating. the page is having the normal behaviour as the standard one.
Thanks in Advance for your help...
public class xxCheckoutDistsCO extends CheckoutDistsCO
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
String UnitId="";
//First get the Application Module
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject vo = (OAViewObject)am.findViewObject("PoRequisitionLinesVO");
String Reqlineid="";
String Linenum="";
String DeliverLoc="";
if(vo.first() !=null)
Reqlineid= vo.first().getAttribute("RequisitionLineId").toString();
Linenum = vo.first().getAttribute("LineNum").toString();
DeliverLoc = vo.first().getAttribute("DeliverToLocationId").toString();
// if(pageContext.isLoggingEnabled(OAFwkConstants.STATEMENT))
// pageContext.writeDiagnostics("TEST >", Reqlineid,1);
// pageContext.writeDiagnostics("TEST >", Linenum,2);
// pageContext.writeDiagnostics("TEST >", DeliverLoc,3);
UnitId=null;
String Querry="select amli_icx_oaf_utils.get_blding_unit_id (?,?,?) from dual";
try
PreparedStatement ps=am.getOADBTransaction().getJdbcConnection().prepareStatement(Querry);
ps.setInt(1,Integer.parseInt(Reqlineid));
ps.setInt(2,Integer.parseInt(Linenum));
ps.setInt(3,Integer.parseInt(DeliverLoc));
ResultSet rs=ps.executeQuery();
// ps.execute();
// am.getOADBTransaction().commit();
while (rs.next())
System.out.println(" Query Results ");
UnitId= rs.getString(1);
System.out.println(" first > ");
rs.close();
ps.close();
catch(SQLException a)
System.out.println(" Error "+a);
System.out.println(" Second > ");
System.out.println(" Third > "); ----the program is executing upto here...it is not setting the value after this.
OAViewObject povo = (OAViewObject)am.findViewObject("PoReqDistributionsVO");
if(povo.getCurrentRow()!=null ) --------If i remove this condition i am getting the nullpointer exception in page.....
System.out.println(" Fourth > ");
povo.getCurrentRow().setAttribute("Attribute12",UnitId);
// if(pageContext.isLoggingEnabled(OAFwkConstants.STATEMENT))
// pageContext.writeDiagnostics("TEST >", UnitId, 1);
Thanks
