How to access the Financial dimensions values in AX2012:

             access the dimensions values in ax2009,  for example

               SalesTable.dimension[0] == Department  value
               SalesTable.dimension[1] == Costcenter  value
               SalesTable.dimension[2] == purpose value
               

        
                             
 code:

    public DimensionValue getDefaultDimensionValue(DimensionDefault _dimensionDefault,Name        _dimensionName)
{
   DimensionAttributeValueSetItemView    dimAttrsetView;
   DimensionAttribute                                   dimensionattr;
   ;
       
  select dimAttrsetView where dimAttrsetView.DimensionAttributeValueSet
          == _dimensionDefault   
    
       join dimensionattr where dimensionattr.RecId == dimAttrsetView.DimensionAttribute
                                && dimensionattr.Name == _dimensionName;
  
                           return dimAttrsetView.DisplayValue;
