TREE report (hierarchy)

Hi,

There is a TREE display report(hierarchy) program having 4 levels (If i press the + sign in the header node then the child node will appear), I want to download when all the nodes are expanded into an excel sheet, i tried System->List->Local File->Excel sheet, but it is not helping me since all the data is displaying in single Column.

i want to Download that output of the tree as it is in the excel sheet, it is nothing but the replica of the output, where we can do the excel manipulations by the data through the report

Please give me any function module available which can satisfy my requirment

Regards

Sudheer
