Row id in editable ALV while using MP_MOD_ROWS

Former Member — Fri, 24 Jun 2011 14:44:00 GMT

Hi Experts

I have an editable alv with 13 fields editable in it. Inside the DATA_CHANGED event i am making use of the attribute MP_MOD_ROWS for doing some specific validations. But I am not able to pass the row_id to the the mehod add_protocal_entry while multiple rows are in MP_MOD_ROWS ,since its not available MP_MOD_ROWS .

Can anyone tell me how i can get the row_id for each row in MP_MOD_ROWS.

Since I need the full row for validations , i cant use MT_MOD_CELLS.

Regards,

Hi,

Try using the method DATA_CHANGED_FINISHED.

Hi.

Thanks for ur response.

But i dont think its possible to call the method add_protocal_entry inside DATA_CHANGE_FINISHED.

My purpose is to get the row ids for each row in MP_MOD_ROWS for highlighting the wrong entries after validations.

You can try then method CHECK_CHANGED_DATA where inside you get the column position and then it calls method DATA_CHANGED.

Hi,

My requirements is as follows.

Suppose I have 5 modified rows in MP_MOD_ROWS out of the 10 rows in the alv grid. I am looping this five rows and doing validations and needs to raise pop up error message using the method add_protocal_entry. Here I need the row_id to pass to the method add_protocol_entry inorder to highlight the wrong entry in each row.

Please advise.

Hi,

this is an excerpt of what we dir:

METHOD handle_data_changed.
...
  FIELD-SYMBOLS:
    <dat> TYPE ANY,
    <mod> TYPE LINE OF lvc_t_modi,
...
  LOOP AT er_data_changed->mt_mod_cells ASSIGNING <mod>.
...
* error case, sy-subrc <> 0 returned by MESSAGE ... RAISING
      symsg2alv_changed_data_prot( ir_cl_alv_changed_data_prot  = er_data_changed
                                   is_modi                      = <mod> ).
      DELETE er_data_changed->mt_mod_cells.
...

using the method

METHOD symsg2alv_changed_data_prot.

  MESSAGE
    ID sy-msgid
    TYPE sy-msgty
    NUMBER sy-msgno
    WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4
    INTO mv_msg. "for debug transparancy
  ir_cl_alv_changed_data_prot->add_protocol_entry(
    i_msgid     = sy-msgid
    i_msgty     = sy-msgty
    i_msgno     = sy-msgno
    i_msgv1     = sy-msgv1
    i_msgv2     = sy-msgv2
    i_msgv3     = sy-msgv3
    i_msgv4     = sy-msgv4
    i_fieldname = is_modi-fieldname
    i_row_id    = is_modi-row_id
*      i_tabix     = i_tabix
       ).

ENDMETHOD.

I do not understand your question about row_id as this is a component lvc_t_modi table. I don't know MP_MOD_ROWS as there is only attribute MT_MOD_ROWS of parameter ER_DATA_CHANGED of event DATA_CHANGED of CL_GUI_ALV_GRID.

After editing all the fields, you can select all the rows you edited and

Use this method of CL_GUI_ALV_GRID class

CALL METHOD r_grid->get_selected_rows

IMPORTING

et_index_rows = gint_selected_rows.

all the selected row indexes will be in gint_selected_rows....

you can use those indexes to read the contents.

Hi,

Check it out,

PUBLIC SECTION.
CLASS-METHODS : m_data_changed FOR EVENT data_changed OF
cl_gui_alv_grid IMPORTING er_data_changed.

CLASS data_changed IMPLEMENTATION.
LOOP AT er_data_changed->mt_mod_cells INTO x_mod_cells.

CALL METHOD er_data_changed->modify_cell
EXPORTING
i_row_id = x_mod_cells-row_id
* i_tabix = x_MOD_CELLS-tabix
i_fieldname = x_mod_cells-fieldname
i_value = x_mod_cells-value
.
IF sy-subrc EQ 0.
MOVE er_data_changed->mt_mod_cells TO itab.
loop at itab INTO xtab.

ENDLOOP.

ENDIF.
ENDLOOP.
endclass.
