Capturing changed data when we press enter in ALV OOPS

Former Member — Mon, 09 Apr 2012 08:50:54 GMT

Hi Folks,

I have built an editable ALV using object oriented approach. when i change data and press SAVE button directly, i can capture the changes by using the method CALL METHOD g_grid->refresh_table_display..

But after changing the data, if i press enter and then press SAVE button, changed data is not captured into my internal table.

Could any body suggest whats the problem.

Thanks,

Shyam.

Hi.

Please try comparing your code with the code given in the below wiki link and see if there are any discrepancies.

Hi,

use method check_changed_data of CL_GUI_ALV_GRID.

like,

take one more itab if required to compare.

data itab_old type standart table of <table>
itab_old[] = itab[].
lr_grid->set_table_for_first_display( .......... ).
when SAVE.
 lr_grid->check_changed_data( ).
if itab_old[] <> itab[]
Update Database.
endif.

Hope this helps u.,

Thanks & Regards,

Kiran.

To make the ALV column as editable in runtime we need to set the field EDIT as part of

field catalog generation.

Whenever the user modifies ALV cell values in runtime and to reflect to change in data

base table we need to handle the event HANDLE_DATA_CHANGED of the class

CL_GUI_ALU_GRID this event is triggered enter key in the modified cell.

By default DATA_CHANGED is not triggered it must be registered explicitly by calling

the method REGISTER_EDIT_EVENT of a class CL_GUI_ALV_GRID.

As part of event DATA_CHANGED we need to import the parameters ER_DATA_CHANGED it is a parameter which is the object of the class CL_GUI_CHANGE_DATA_PROTOCOL.
As part of the above class we need to use instance attribute MT_MOD_CELLS (OR)

MT_GOODS_CELLS which are of type LVC_T_MODI. It is table type associated with the structure LVC_S_MODI.

These attributes contains a information related to be modified cell the information include

row id, field name, and value.

this is some sample which includes all the functionality PFA
