Organisation Structure report

Hi OM experts,

Altough SAP has provided various reports but i need one report to give the details of organization units under a selected organization unit.

I have created one report through SAP Query by using standard infoset but O/P is not displayed as per the the requirements, Highest level Org Unit should come at Top and then further Org Units...

System is displaying result on the Org Unit ID number (Ascending Order).

How i can create such report ?

Thanks

Puneet
