Save changes in alvgrid

Former Member — Fri, 29 Sep 2006 15:01:18 GMT

Hi all,

In my alvgrid I have few columns which are editable, i edit cells, insert a new row and modify row and delete.

All these changes should be stored in internal table. I should save automaticaly when i invoke display button.

I use this code but i need the modification without tranporting the fields how do i do?

WHEN 'DISPLAY'.

PERFORM changed_data.

PERFORM filter_condpri.

WHEN 'SAVE'.

PERFORM save_data.

ENDCASE.

ENDMODULE. "pai_100 INPUT

&----

*& Module exit_0100 INPUT

MODULE exit_0100 INPUT.

CASE ok_code.

WHEN 'EXIT'.

LEAVE PROGRAM.

ENDCASE.

ENDMODULE. " pai_100 INPUT

&----

*& Form changed_data

FORM changed_data.

LOOP AT gt_zflp_ttcualcond

Hello

I do not fully understand what do you mean by "... need the modification without tranporting the fields...".

Does this mean that you want to know the changes yet when the ALV list is in display mode the unmodified entries should be displayed? This does not make sense to me.

In any case, you should call method CHECK_DATA_CHANGED at PAI. This will raise event DATA_CHANGED for which you should have defined an event handler method (e.g. HANDLE_DATA_CHANGED). This method has an IMPORTING parameter er_data_changed. This object has all information about the changes in the ALV grid:

- er_data_changed->mt_mod_cells == modified cells

- er_data_changed->mp_mod_rows == data object with modified row

- er_data_changed->mt_deleted_rows == deleted rows

- er_data_changed->mt_inserted_rows == inserted rows

Thus, you simply have to analyse these attribute of the er_data_changed object to find out what the user changed on the ALV grid.

Regards

Uwe

Hello Uwe,

You are right. We can use with these importing parameters.

My question is : i want to store the modified rows & new inserted row in internal table.

I have a user defined button where I invoke this data_changed form, here i need all the modifed rows and inserted row to be saved before i click on save button. How do i do this?

I have another save button in tool bar where I invoke this for saving the modified fields in database table.

Waiting for your reply.

Regards

sap team.

As have been told by Uwe

you need to use the

Method Check_Changed_Data in the PAI part.

Just cut and paste the following code it should be working after that.

data : l_valid type c value ' ',

l_refresh type c value ' '.

call method g_grid0100->check_changed_data

importing

e_valid = l_valid

changing

c_refresh = l_refresh.

Cheers

Hi sushi,

I did as you said but there is no success. The values are not retained when i press "display" button.

1st time when i press "display" the 1st values I show in alvgrid. I try to change them.

2nd time when i press "display" another set of values I show. at this moment interanlly, I should retain the 1st changed values in internal table..

How do i do this? Please help me out.

Regards

Madhavi.

Hi,

Check the sample code:

is_layout = p_layout

it_toolbar_excluding = i_excl_func

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.

* 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.
