save changes automatically in alvgrid

Former Member — Wed, 27 Sep 2006 09:12:24 GMT

Hello all,

How do i save changes automatically in alvgrid. I display data with fields which can be editable & some which are not.

The fields which are editable should be saved automatically. These fields should be saved in global internal table.

I have save button, but I invoke only when the changed data is saved in database table via global internal table.

Looking forward for your reply.

regards

Madhavi.

You have to use the method "CHECK_CHANGED_DATA" for this purpose.

Check the standard SAP program BCALV_EDIT_04 FOR YOUR REFERENCE.

Check the sample code:

*-- Display Report

CALL METHOD o_alvgrid->set_table_for_first_display

EXPORTING

i_save = c_a

is_layout = p_layout

it_toolbar_excluding = i_excl_func

CHANGING

it_outtab = p_output[]

it_fieldcatalog = p_fieldcat[]

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4.

IF sy-subrc <> 0.

MESSAGE s001(zesspa) WITH text-029. " Error in Displaying

LEAVE LIST-PROCESSING.

ELSE.

<b>* Register events

CALL METHOD o_alvgrid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

CALL METHOD o_alvgrid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

This registering event will make the data changes to be automatically update to the internal table.

Then write the code in the data changed event to modify the global internal table.

Hi ravi,

I use data changed for cell this code..

handle_data_changed2

FOR EVENT data_changed OF cl_gui_alv_grid

IMPORTING er_data_changed

e_onf4_before

e_onf4_after.

In which class this "check_changed_data" present.

Hello Prakash,

You are right I use the call method

CALL METHOD o_alvgrid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

but not this :-

CALL METHOD o_alvgrid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

This is my present code.. can you have alook on this..

METHOD handle_data_changed1.

FIELD-SYMBOLS: <myname> TYPE ANY.

DATA: lv_fieldname(30).

*instance of internal table grid..

DATA lt_mod_cells TYPE lvc_t_modi.

DATA ls_mod_cells TYPE lvc_s_modi.

for grid table..

DATA ls_flp_cualcond TYPE zflp_stcualcondpri.

DATA lv_tabix TYPE sytabix.

assign methods to a variable..

lt_mod_cells = er_data_changed->mt_mod_cells.

LOOP AT lt_mod_cells INTO ls_mod_cells.

read values from gt_zflp_ttcualcondpri..

READ TABLE gt_zflp_ttcualcond INTO ls_flp_cualcond

INDEX ls_mod_cells-row_id.

CONCATENATE 'LS_FLP_CUALCOND-' ls_mod_cells-fieldname

INTO lv_fieldname.

ASSIGN (lv_fieldname) TO <myname>.

<myname> = ls_mod_cells-value.

move the the cells

MOVE ls_mod_cells-row_id TO lv_tabix.

IF ls_flp_cualcond-chflg NE 'I'.

ls_flp_cualcond-chflg = 'M'.

ENDIF.

*modify internal table..

MODIFY gt_zflp_ttcualcond

FROM ls_flp_cualcond

INDEX lv_tabix.

ENDLOOP.

FREE er_data_changed.

implement the method in alvgrid class.

CALL METHOD grid1->refresh_table_display.

LEAVE TO SCREEN '0100'.

ENDMETHOD. "handle_data_changed1

Looking forward.

Thank you

Madhavi.

Don't free the er_data_changed, some time that may cuase the problem. Also there is no need of LEAVE TO SCREEN '0100'.

Also use the below method after calling the set_table_for_first_display.

CALL METHOD o_alvgrid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

Prakash.

Also while looping at loop at lt_mod_cells INTO ls_mod_cells, u will directly get the field in which the change is happened. So no need of code like this:

CONCATENATE 'LS_FLP_CUALCOND-' ls_mod_cells-fieldname

INTO lv_fieldname.

ASSIGN (lv_fieldname) TO <myname>.

<myname> = ls_mod_cells-value.

move the the cells

MOVE ls_mod_cells-row_id TO lv_tabix.

check in debugging mode whethere data's are updated to the internal table.

Regards,

Prakash.

Hello Madhavi,

When you are using the editable field in ALV.

1) frist, catch the fields or row with key fields.

2) update/modify the itab/dbtab with the help of key fields. when input is done.

That should fix the problem

thanks
