How add financial dimension on forms inside Ax 2012

Step 1: Form ClassDecleration

public class FormRun extends ObjectRun

      {

     

          DimensionDefaultingController   dimensionDefaultingControllerHeader;

          DimensionDefaultingController   dimensionDefaultingControllerLine;

          DimensionDefaultingController   dimensionDefaultingController;

      }

Step 2: Form Init()

   

      public void init()

      {

          super();

     

          

DimensionDefaultingController::constructInTabWithValues(true,true,true,0, this,DimensionsFastTab,"@SYS14926");

          dimensionDefaultingController.parmAttributeValueSetDataSource(BiddingMainCostSheetTable_ds,fieldstr(BiddingMainCostSheetTable, DimensionDefault));

          dimensionDefaultingController.pageActivated();

      }

   

Step 3: Data source

       

      public void delete()

      {

          ;

     

          ttsbegin;

     

          element.numberSeqFormHandler().formMethodDataSourceDelete();

     

     

          super();

          dimensionDefaultingController.deleted();

          //

          ttscommit;

      }

Step 4: Data source

   

      public void write()

      {

     

          ttsbegin;

                    dimensionDefaultingController.writing();

         

         

          super();

          element.numberSeqFormHandler().formMethodDataSourceWrite();

     

          ttscommit;

          //

     

      }

Step 5: Data source active()

     

      public int active()

      {

          int ret;

     

          ret = super();

     

          

             dimensionDefaultingController.activated();//true);

     

          return ret;

      }

Step 6: Design Tab-> Tabpage

  

      public void pageActivated()

      {

          dimensionDefaultingController.pageActivated();
