repeating data when export to excel

Hi,

             I have a ssrs report which is having 3 row groups in parent child group format.Child will display based on the toggling on parent.Also,

I have subtotal for each group(inside the group).The problem i am facing is,When i export that toexcel, the row group values are repeating.

Eg:  

          Region         region         |location            |Sales

           R1               | s1                    |l1                      |1000

                                subregionTotal                           | 1000

                              |s1                                               |  1000  

          RegionTotal                                                    | 1000    

          R1                                                                     |1000                         

Here u can see,R1 and s1 are repeating.

The data wont repeat, if i remove the toggle option in the row group property or if i add subtotal outside of each group.And

this problem i am facing only after exporting to Excel.

Thanks.

Thanks.
