Input Fields in ALV

Former Member — Wed, 28 Sep 2005 09:10:35 GMT

Hi,

I displayed a ALV list wich some fields ready for input.

The problem I'm facing is, when I enter a value in, for example TEXT ITEM, I can easly catch the new value. But when I change a field wich is DATE FORMAT i don't see the changes and therefore can't update the value in my table.

Thanks,

Joseph

Hi Joseph,

I hope you are might using the event data_changed where you will be getting a object er_data_changed an object of cl_alv_changed_protocol

which has a table mt_mod_cells which will have the changed or inserted records.

No I'm using FM REUSE_ALV_HIERSEQ_LIST_DISPLAY.

You should be using

handle_data_changed FOR EVENT data_changed OF cl_gui_alv_grid IMPORTING

er_data_changed.

Inside the Handle_Data_changed method,

Use the methods get_cell_value exporting ls_mod_cell-row_id to get the changed value and validate.

But that means that I should change my program from using FM REUSE_ALV_HIERSEQ_LIST_DISPLAY to CALL METHOD.

I dont know who to do it without Call Method. Please go to Se80 -> Packages -> SLIS. In that , look out for an example program BCALV_EDIT_03.

I hope this solves ur problem.

hi, you can't get the user inputted from ALV?

have you tried this way?


DATA:
LC_GLAY TYPE LVC_S_GLAY.
 
* this is the critical point 
LC_GLAY-EDT_CLL_CB = 'X'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
     EXPORTING
       I_GRID_SETTINGS = LC_GLAY
       IT_FIELDCAT = L_ALV_FILEDCAT
     TABLES
       T_OUTTAB = ITAB.

hope it will be helpful

Hi,

You can do editable alv using set_table_for_first_display.

struct_grid_lset TYPE lvc_s_layo,

i_grid_fcat TYPE lvc_t_fcat

DATA ls_fcat TYPE lvc_s_fcat.

CLEAR ls_fcat.

ls_fcat-fieldname = 'DATE'.

ls_fcat-ref_table = 'TYPE'.

ls_fcat-ref_field = 'C'.

ls_fcat-edit = 'X'.

ls_fcat-coltext = text-030."Date

ls_fcat-seltext = text-030.

APPEND ls_fcat TO p_i_grid_fcat.

CALL METHOD o_grid->set_table_for_first_display

EXPORTING

i_bypassing_buffer = space

is_variant = ws_f_grid_disvar

i_save = ws_c_grid_save

is_layout = struct_grid_lset

CHANGING

it_outtab = i_grid_outs[]

it_fieldcatalog = i_grid_fcat[]

it_sort = i_sort_fcat. " Period

Also Check this code.Another way using field symbols.

i_fieldcat TYPE lvc_t_fcat,

w_layout TYPE lvc_s_layo ,

w_variant TYPE disvariant.

FIELD-SYMBOLS : <lfs_fieldcat> TYPE lvc_s_fcat.

*Default display

LOOP AT p_fieldcat ASSIGNING <lfs_fieldcat>.

CASE <lfs_fieldcat>-fieldname.

WHEN 'DATE'.

<lfs_fieldcat>-coltext = text-050.

<lfs_fieldcat>-no_out = ' '.

<lfs_fieldcat>-scrtext_l = text-050.

<lfs_fieldcat>-edit = 'X'.

WHEN OTHERS.

ENDCASE.

ENDLOOP.

Hope it helps you,
