Hi,

In case of oops ALV u can do the following,

Create a class :-

CLASS cl_event_receiver DEFINITION.

PRIVATE SECTION.

DATA: error_in_data TYPE c.

METHODS

perform_checks

IMPORTING

pr_data_changed TYPE REF TO cl_alv_changed_data_protocol.

METHODS:

get_cell_values

IMPORTING

row_id TYPE int4

pr_data_changed TYPE REF TO cl_alv_changed_data_protocol

EXPORTING

w_key TYPE cuinst.

ENDCLASS.

under which create a method:-

CLASS cl_event_receiver IMPLEMENTATION.

METHOD handle_data_changed.

error_in_data = space.

CALL METHOD perform_checks( er_data_changed ).

IF error_in_data = 'X'.

CALL METHOD er_data_changed->display_protocol.

ENDIF.

ENDMETHOD. "handle_data_changed

METHOD get_cell_values.

CALL METHOD pr_data_changed->get_cell_value

EXPORTING

i_row_id = row_id

i_fieldname = 'CARRID'

IMPORTING

e_value = w_key.

ENDMETHOD. "GET_CELL_VALUES

ENDCLASS.

METHOD perform_checks.

PERFORM data_checks USING pr_data_changed

CHANGING error_in_data.

ENDMETHOD. "perform_checks

Then in the subroutine part:-

FORM data_checks USING pr_data_changed

CHANGING error_in_data.

FIELD-SYMBOLS: <l_fs> TYPE ANY.

LOOP AT p_data_changed->mt_mod_cells INTO ls_good.

CLEAR:l_htype.

CASE ls_good-fieldname.

WHEN 'FIELDNAME'

CHECK ls_good-value IS NOT INITIAL.

IF sy-subrc NE 0.

PERFORM add_entry USING text-m02 ls_good-fieldname

ls_good-row_id p_data_changed.

p_error = 'X'.

ENDIF.

FORM add_entry USING p_text p_fieldname p_rowid

p_data_changed TYPE REF TO

cl_alv_changed_data_protocol.

CALL METHOD p_data_changed->add_protocol_entry

EXPORTING

i_msgid = '0K'

i_msgno = '000'

i_msgty = 'E'

i_msgv1 = p_text

i_fieldname = p_fieldname

i_row_id = p_rowid.

ENDFORM . "ADD_ENTRY

endcase.

ENDLOOP.

ENDFORM.

Revert back in case of further help.

Thanks & Regards,

Hi,

This code will reflect changed from alv to the internal table.

If you make any changes in alv grid output, then these changes will be reflected back to internal table

* to reflect the data changed into internal table
DATA : ref_grid TYPE REF TO cl_gui_alv_grid. "new

IF ref_grid IS INITIAL.
  CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
    IMPORTING
      e_grid = ref_grid.
ENDIF.
 
IF NOT ref_grid IS INITIAL.
  CALL METHOD ref_grid->check_changed_data.
ENDIF.

Hope this helps you.

Regards,

Tarun
