Unable to retrieve result from Order Entry Orders query

Hi,

XXX is an order id which exists in our environment. I ran the below script in a BS. BO and BC used here are vanilla objects.if(FirstRecord()) is not satisfied. So i looked into the query and found that  S_ORDER_POSTN.POSTN_ID = :2 an extra query is being added, which i havnt added in the search spec below.

var OrderBO:BusObject = TheApplication().GetBusObject("Order Entry (Sales)");

or

var OrderBO:BusObject = TheApplication().GetBusObject("Order Entry");

var OrderBusC:BusComp = OrderBO.GetBusComp("Order Entry - Orders");

var sCIMAOrderId="XXX";

with (OrderBusC)

{

     SetViewMode("AllView");

       ActivateField("Order Number");

       ClearToQuery();

       SetSearchSpec("Id", sCIMAOrderId);
