Display a dynamically generated table as a tree

Hi everyone,

the document http://scn.sap.com/docs/DOC-53788 describes how to display a dynamically generated table (using RTTS) as a list (class cl_salv_table). This works, but I would like to display a dynamic table as a tree (class cl_salv_tree). Unfortunately it doesn't work for me. I'm getting cx_salv_error. Does anybody know how to do this?

TRY.

cl_salv_tree=>factory(

IMPORTING

r_salv_tree = lo_salv_tree

CHANGING

t_table = <fs_table> ).

CATCH cx_salv_data_error INTO lo_data_err.

CATCH cx_salv_not_found INTO lo_not_found.

CATCH cx_salv_error INTO lo_error.

ENDTRY.

Thanks.
