[Former Member]

Hi,

How do i save back the modified values back to the internal table from ALV?

Hi,

First register_edit_event for registering the changes done.

Use refresh_table_display of alv grid for refreshing the grid.

Check this tutorial.

Hi,

You can create a button in PF-STATUS on which the user will click to save data.

Now,at user-command check if you sy-uccom matches with the function code of save button.If so then call a perform save_data.

Form save_data.

CALL METHOD grid1->check_changed_data

IMPORTING

e_valid = l_valid.

The internal table trhat you have passed in the output contains the changed data now.Now you can proceed as you need.

Hi Prabha.

While preparing field catalog you have to set edit field as in this code.

ls_fcat-fieldname = 'VBELN'.

ls_fcat-ref_table = 'VBAK'.

ls_fcat-ref_field = 'VBELN'.

ls_fcat-coltext = 'Sales order'.

<b> ls_fcat-edit = 'X'.</b>

APPEND ls_fcat TO gt_fieldcat_edit.

you can use check_changed_data method on alv object to fetch the changed data

Hope this helps

Hi Prabha

In the PAI when a user event occurs u call the method

grid object->checked_changed_data.

this will raise the event data_changed.

you write a method for data_changed event as follows

METHOD HANDLE_DATA_CHANGED.

in that you will get an object called er_data_changed that will have an internal tables MT_MOD_CELLS which have modified record you can read that .

LOOP AT ER_DATA_CHANGED->MT_MOD_CELLS INTO LS_MOD_CELLS.

Please reward if useful.
