Fill tree from webdynpro code

Hi masters.
I need to fill a tree.

I execute a bapi from webdynpro when i clicked a button, this bapi retrieves two internal tables.
Those Internal tables are related, so i need to pass them from a tree.

Note: I already saw the webdynpro demo programs and one uses supply function and another is really complex.

Someone have an example in code how to fill a tree ??

The requiriment is really similar to DEMOTREE. ( but i need wothout supply functions).

Thanks

    Well, you can also use a Table with a Row Arragement to create a Tree structure.

      Hi

      Follow the below steps,

      ->Create nodes(for ex. Billing Head & Billing Item). Note: Item node should not be Singleton.

      Below code used to fill the tree after the action

      TYPES: BEGIN OF ts_vbrk,
      vbeln TYPE vbrk-vbeln,
      END OF ts_vbrk.

      TYPES: BEGIN OF ts_vbrp,
      vbeln TYPE vbeln,
      posnr TYPE posnr,
      fkimg TYPE fkimg,
      vrkme TYPE vrkme,
      END OF ts_vbrp.

      DATA lt_vbrp TYPE TABLE OF ts_vbrp.
      DATA ls_vbrp TYPE ts_vbrp.

      DATA lt_vbrk TYPE TABLE OF ts_vbrk.
      DATA ls_vbrk TYPE ts_vbrk.

      DATA ln_head TYPE REF TO if_wd_context_node.
      DATA le_head TYPE REF TO if_wd_context_element.
      DATA lt_head TYPE wd_this->elements_bill_head.
      DATA ls_head TYPE wd_this->element_bill_head.

      DATA ln_item TYPE REF TO if_wd_context_node.
      DATA lt_item TYPE wd_this->elements_bill_item.
      DATA ls_item TYPE wd_this->element_bill_item.

      ln_head = wd_context->path_get_node( wd_this->wdctx_bill_head ).

      SELECT vbeln
      FROM vbrk
      INTO TABLE lt_vbrk
      UP TO 10 ROWS.

      IF sy-subrc EQ 0.

      SELECT vbeln posnr
      FROM vbrp
      INTO TABLE lt_vbrp
      FOR ALL ENTRIES IN lt_vbrk
      WHERE vbeln EQ lt_vbrk-vbeln.

      IF sy-subrc EQ 0.

      ln_head->bind_table( lt_vbrk ).

      LOOP AT lt_vbrk INTO ls_vbrk.

      le_head = ln_head->get_element( sy-tabix ) .
      ln_item = le_head->get_child_node( wd_this->wdctx_bill_item ).

      IF le_head IS NOT INITIAL AND ln_item IS NOT INITIAL.

      CLEAR lt_item.

      LOOP AT lt_vbrp INTO ls_vbrp WHERE vbeln = ls_vbrk-vbeln.

      CLEAR ls_item.
      MOVE-CORRESPONDING ls_vbrp TO ls_item.

      APPEND ls_item TO lt_item.

      ENDLOOP.

      ln_item->bind_table( lt_item ).

      ENDIF.

      ENDLOOP.

      ENDIF.

      ENDIF.

      Thanks & Regards
