Edit and save dynamic alv.

[former_member618731]

Hi Experts

I have created a dynamic table then filled this dynamic table with the help of field symbols and then passed this dynamic table to grid1->set_table_for_first_display and hence the dynamic alv is shown on the screen. Now, can I do something to make this alv editable and store these values in z table. I have tried the method get_changed_cell method, but no help.

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
    EXPORTING
      IT_FIELDCATALOG = LT_LVC_CAT
    IMPORTING
      EP_TABLE        = LP_TABLE.

  ASSIGN LP_TABLE->* TO <LT_DATA>.


*Create structure = structure of the internal table
  CREATE DATA LP_STRUCT LIKE LINE OF <LT_DATA>.
  ASSIGN LP_STRUCT->* TO <HEADER>.

*  SORT gt_data BY erdat.
*sort IT_VEWAO by MATNR.

  LOOP AT IT_VEWZO INTO WA_VEWZO.

    AT NEW VKBUR.
      CLEAR <HEADER>.
*
      ASSIGN COMPONENT 'VKBUR' OF STRUCTURE <HEADER> TO <FIELD>.
      IF SY-SUBRC NE 0.
        EXIT .
      ENDIF.
      <FIELD> = WA_VEWZO-VKBUR.
    ENDAT.

    MOVE WA_VEWZO-PD_HIER  TO L_COL.

    ASSIGN COMPONENT L_COL OF STRUCTURE <HEADER> TO <FIELD>.

    IF SY-SUBRC NE 0.
      EXIT .
    ENDIF.
    <FIELD> = WA_VEWZO-PLAN_QTY.

    CONCATENATE WA_VEWZO-PD_HIER '_AP' INTO WA_VEWZO-PD_HIER .
    MOVE WA_VEWZO-PD_HIER  TO L_COL.

    ASSIGN COMPONENT L_COL OF STRUCTURE <HEADER> TO <FIELD>.

    IF SY-SUBRC NE 0.
      EXIT .
    ENDIF.
    <FIELD> = WA_VEWZO-APROV_QTY.


**********************************************************************
    AT END OF VKBUR.
      APPEND <HEADER> TO <LT_DATA>.
*
    ENDAT .

  ENDLOOP.

Hi ,

You have to call checked_changed_data method of cl_gui_alv_grid which will call your handle data changed method for event data_changed.

Hi,

What help u need?

to activate the editable field u need to pass the field catalog parameter

EDIT = 'X'

Then Edit values in your alv

and press enter or define any icons in ur alv list useing user command

check the changed values using the method

CALL METHOD g_alvgrid1->check_changed_data( ).

It will help you i think.

Thanks, but I guess this will only verify the value that has been changed not the information about what field has been changed.

What I am trying to figure out is how to get the information on what all cells have been changed and also the new value.

If you implement the DATA_CHANGED event you can get the information of what cell and what is the value changed.

data_changed         for event data_changed
                         of cl_gui_alv_grid
                         importing er_data_changed "<---This holds the information
                                   e_onf4
                                   e_onf4_before
                                   e_onf4_after,

er_data_changed is of type CL_ALV_CHANGED_DATA_PROTOCOL, so here you can find the Following information from the attributes of the object.

MT_MOD_CELLS

MP_MOD_ROWS

MT_GOOD_CELLS

MT_DELETED_ROWS

MT_INSERTED_ROWS

Hello Vijay,

I am too trying to get the changed values. I read your reply to this post. Can you please give the detaile description as how the data_changed method can be used? I created object of class cl_gui_alv_grid. And when i said

call method obj->data_changed

importing

er_data_changed.

It gives error that "data_changed might be protected or private".

What to do? as i am not quite familiar with OO ABAP.
