Recently I start to study SD and I found the product hierarchy in transaction code V/76 could not be viewed in tree style and it is not so convenient to check:
So I wrote a simple report to retrieve hierarchy data from table T179 and display the data in a tree as below:
The source code of report is listed below:REPORT zdisplay_hierarchy.
REPORT zdisplay_hierarchy.
DATA: g_alv_tree TYPE REF TO cl_gui_alv_tree,
gt_data TYPE STANDARD TABLE OF zcl_alv_tool=>ty_displayed_node,
ok_code LIKE sy-ucomm,
save_ok LIKE sy-ucomm,
ls_data LIKE LINE OF gt_data.
END-OF-SELECTION.
DATA(lo_tool) = NEW zcl_alv_tool( ).
DATA(lt_fieldcat) = lo_tool->get_fieldcat_by_data( ls_data ).

And drag a custom container to screen with name “CCONTAINER1”:
