TREE ALV with separate header line

Hi Experts,

My req is to display an alv in a tree structure with separate header name.

I found all the examples in SDN which has the same header name.only values are displayed into the next expand.

little explanation: when i expand my tree the displayed line have a separate header.

in first line if i have vendor code, vendor name etc,

then after expanding the vendor code separate header line will come like subrange code , subrange name etc, and under the header the corresponding values.

again when i expand the subrange code another header will come with partner type, partner name etc.and the corresponding values under the header.

Any idea or any examples.

Thanks,

Jo
