How to change the lov query??

Question

Hi Friends,
I am trying to extend a controller of the base page to change the lov query. I am not able to get the lov VO since I am not getting the lov AM in the controller.
I want to use the setQuery() to set the lov query programatically in base class controller PR.
My controller code looks like ::
OAApplicationModule am = oapagecontext.getRootApplicationModule();
oapagecontext.writeDiagnostics(this,"The Root AM is : " + am.toString(),6); // displaying oracle.apps.icx.por.req.server.RequisitionAMImpl
OAApplicationModule lovAM = (OAApplicationModule)am.findApplicationModule("RequisitionLovAM"); // Returning Null
OAViewObjectImpl vo = (OAViewObjectImpl)lovAM.findViewObject("ReqSupplierVO");
String seededQuery = vo.getQuery();
oapagecontext.writeDiagnostics(this,"Seeded Query for ReqSupplierVO is "+ seededQuery,6);
String customQuery = "new_query" // here i m writing my new query.
vo.setQuery(customQuery); // setting my custom query.
oapagecontext.writeDiagnostics(this,"Custom Query for the ReqSupplierVO is "+ vo.getQuery(),6);
The following are the details.
Base Page : /oracle/apps/icx/icatalog/shopping/webui/NonCatalogRequestPG
Base Page Controller : logi.oracle.apps.icx.icatalog.shopping.webui.NonCatalogRequestCO
Lov Region : /oracle/apps/icx/lov/webui/ReqSupplierLovRN
Lov Controller : oracle.apps.icx.lov.webui.ReqSupplierLovCO
Lov VO : oracle.apps.icx.lov.server.ReqSupplierVO ( i want to remove outer join in this VO query )
I cant extend the lov controller since the same lov region is using in other pages also where i dont want apply my new lov query.
Is the way i am trying is correct? How can i get the Lov AM in the base page? Any help highly appreciated.

Hi Pratap,
Thanks for coming back on this.
The background of this customization is, We are implementing AME and are trying to restrict the number of approvers in the Change First Approver LOV (ApprroverLovVO.xml) based on company code and cost centre during the creation of Requistion. At the moment, the LOV is bringing back every employee who has a valid WF role.
At the moment (up till I saw this thread) I was trying to customize ReqApprChfCo.java by adding this code to processRequest method
OAMessageLovInputBean CompanyCode = (OAMessageLovInputBean)oawebbean.findIndexedChildRecursive("ChargeAccountFlex0_column"); //this is returing null
OAMessageLovInputBean CostCentre = (OAMessageLovInputBean)oawebbean.findIndexedChildRecursive("ChargeAccountFlex1_column"); //this is returing null
RequisitionLovAMImpl am = (RequisitionLovAMImpl)oapagecontext.getApplicationModule(oawebbean); // this is returning null
OAViewObject approverLovVO = (OAViewObject)oam.findViewObject("ApproverLovVO");
Then, once found to append the viewobject with where clause. Was this the right method of achiving it, or to create a new custom VO and region?
