OO Transaction With Docking Containers

[Former Member]

Hi,

I have developed a OO Transaction with two docking containers. On the left docking container, I have a tree and on the screen I have some fields which are in invisible mode.

My requirement is, Whenever user double clicks on a respective node in the tree, I need to get the screen on the right hand side and with the fields in disable mode.

I can able to capture the event when the user double clicks. But I could not able to enable fields on the screen.

Here is the sample code.

CALL METHOD LO_ALV_TREE->GET_SELECTED_ITEM

IMPORTING

E_SELECTED_NODE = LV_SELECTED_ITEM

E_FIELDNAME = LV_FIELDNAME

EXCEPTIONS

NO_ITEM_SELECTION = 1

CNTL_SYSTEM_ERROR = 2

FAILED = 3

others = 4.

IF SY-SUBRC <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

READ TABLE lty_t_node_ref INTO lv_t_node_ref WITH KEY NODE_NO = LV_SELECTED_ITEM.

IF lv_t_node_ref-EVENT IS NOT INITIAL.

Message i001(i) with 'Double click FROM' lv_t_node_ref-EVENT.

loop at screen.

screen-input = 1.

modify screen.

endloop.

if you are talking about trees , just check this approach.

SAPSIMPLE_TREE_CONTROL_DEMO

SAPLIST_TREE_CONTROL_DEMO

SAPCOLUMN_TREE_CONTROL_DEMO

i am still doubtful what you are showing on the other side. is it a grid report.

Hello Srinivas

Your coding sample is incomplete because we do not know when this coding is executed.

Assuming that this is part of your event handler method (HANDLE_DOUBLE_CLICK) then the MODIFY SCREEN statement(s) are at the wrong place.

Below you find my suggestion:

METHOD handle_double_click. " implementation

CALL METHOD LO_ALV_TREE->GET_SELECTED_ITEM
IMPORTING
E_SELECTED_NODE = LV_SELECTED_ITEM
E_FIELDNAME = LV_FIELDNAME
EXCEPTIONS
NO_ITEM_SELECTION = 1
CNTL_SYSTEM_ERROR = 2
FAILED = 3
others = 4.
IF SY-SUBRC 0.

    * MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
    * WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

READ TABLE lty_t_node_ref INTO lv_t_node_ref WITH KEY NODE_NO = LV_SELECTED_ITEM.

" Store event in global variable, e.g.:
  gd_event = lv_t_node_ref-EVENT.

" Trigger PAI of the dynpro
    CALL METHOD cl_gui_cfw=>set_new_ok_code
      EXPORTING
        new_code = 'DUMMY'.


ENDMETHOD.

Logic in PBO module:

  MODULE modify_screen.

    CHECK ( gd_event IS NOT INITIAL ).

Message i001(i) with 'Double click FROM' lv_t_node_ref-EVENT.
loop at screen.
screen-input = 1.
modify screen.
endloop.

  ENDMODULE.
