显示SAP CRM Product hierarchy的一个小工具

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.
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 ).
  PERFORM change_label.
  CALL SCREEN 100.
MODULE pbo OUTPUT.
  SET PF-STATUS 'MAIN100'.
  SET TITLEBAR 'MAINTITLE'.
  IF g_alv_tree IS INITIAL.
  PERFORM init_tree.
  CALL METHOD cl_gui_cfw=>flush

  cntl_system_error = 1
  cntl_error = 2.
  ASSERT sy-subrc = 0.
  ENDIF.
ENDMODULE. " PBO OUTPUT
MODULE pai INPUT.
  save_ok = ok_code.
  CLEAR ok_code.
  CASE save_ok.
  WHEN 'EXIT' OR 'BACK' OR 'CANC'.
  PERFORM exit_program.
  WHEN OTHERS.
  CALL METHOD cl_gui_cfw=>dispatch.
  ENDCASE.
  CALL METHOD cl_gui_cfw=>flush.

  READ TABLE lt_fieldcat ASSIGNING FIELD-SYMBOL(<id>) INDEX 1.

  <text>-scrtext_s = 'Text'.
  <text>-outputlen = 40.
ENDFORM.
FORM init_tree.
  g_alv_tree = lo_tool->get_tree( ).
  DATA l_hierarchy_header TYPE treev_hhdr.
  PERFORM build_hierarchy_header CHANGING l_hierarchy_header.
  CALL METHOD g_alv_tree->set_table_for_first_display
  EXPORTING
  is_hierarchy_header = l_hierarchy_header

  it_fieldcatalog = lt_fieldcat
  it_outtab = gt_data.
  PERFORM create_tree.
  g_alv_tree->frontend_update( ).
  lo_tool->expand( ).
ENDFORM.
FORM create_tree.
  DATA(lt_data) = lo_tool->get_hierarchy_data( ).
  lo_tool->draw_tree( lt_data ).
ENDFORM. " init_tree
FORM build_hierarchy_header CHANGING p_hierarchy_header TYPE treev_hhdr.
  p_hierarchy_header-heading = 'Material hierarchy'.
  p_hierarchy_header-width = 30.
  p_hierarchy_header-width_pix = ' '.
ENDFORM. " build_hierarchy_header
FORM exit_program.
  LEAVE PROGRAM.
ENDFORM. " exit_program

In order to use the report, all you need is to just create a new screen :

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