Preserve Hierarchy when WEBI Results exported to Excel

Hi,

1) Drilldown functionality in Hierarchy works fine in WEBI Report. However when we export this data to Excel,  drilldown feature does not work.

2) Hierarchy Indention is not consistent across child note in WEBI. For ex

Node 1

           Child 1

           Child 2

           Child 3

      Child 4

Please note that indentation of Child 4 is not same as Child 1 through Child 3.

Please advice on above issue.

Regards,

Shridevi B
