Problems in ALV

[Former Member]

I copy a pf status from FG SALV and set 2 buttons in it, ADD & DELETE. But when I press the butten created by myself, the internal table of the data didn't reflesh, that is , the user's action didn't take any effect. For example, I changed one column in the internal table from 3 to 2, when I debugged and I found the value of the internal table was still 3.

The internal table was g_t_alv in this case.

My code is the following:

call function 'REUSE_ALV_GRID_DISPLAY_LVC'

exporting

i_callback_program = sy-repid

i_callback_pf_status_set = 'SUB_PF_STATUS_SET'

i_callback_user_command = 'SUB_USER_COMMAND'

is_layout_lvc = l_layout

it_fieldcat_lvc = l_t_fieldcat[]

tables

t_outtab = g_t_alv

exceptions

program_error = 1

others = 2.

Hi,

Use the below methods and FM

CALL METHOD gr_alvgrid_100_1->set_table_for_first_display

EXPORTING

is_layout = gs_layout

CHANGING

it_outtab = git_po_temp

it_fieldcatalog = gt_fieldcat_100_1

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4.

*--Input field can be modified

CALL METHOD gr_alvgrid_100_1->set_ready_for_input

EXPORTING

i_ready_for_input = 1.

• register enter key event

CALL METHOD gr_alvgrid_100_1->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

• register field modified event

CALL METHOD gr_alvgrid_100_1->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

ELSE.

USE this methods

DATA : lv_ref1 TYPE REF TO cl_gui_alv_grid.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

e_grid = lv_ref1.

CALL METHOD lv_ref1->check_changed_data.

Now u can check the changed avlues..

Hi ,

I hope you have a check box to select the records to be deleted .

gs_glay-edt_cll_cb = 'X'.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = sy-cprog

it_fieldcat = gi_fieldcat

i_grid_settings = gs_glay

• i_grid_title = 'Create Condition Record '

i_grid_title = gv_text

i_callback_pf_status_set = 'SET'

i_callback_user_command = 'USER_COMMAND'

i_default = 'X'

i_save = 'X'

TABLES

t_outtab = gi_display

EXCEPTIONS

program_error = 1

OTHERS = 2.

IF sy-subrc <> 0.

WRITE: text-005.

ENDIF.

You have to write the code for the delete button in " form user_command".

The selected records will have X in the checkbox column .

Hi ,

Add a column in the internal table for check box .

Hi,

Add Refresh button and add function code '&REFRESH' to that button.

After changing the value on the output. Refresh using created button.

You can check the changed value in the table in the user_command when you double click on the output.

*&---------------------------------------------------------------------*
*&      Form  USER_COMMAND
*&---------------------------------------------------------------------*
FORM user_command  USING r_ucomm     LIKE sy-ucomm  rs_selfield TYPE slis_selfield.
  IF r_ucomm = '&IC1'.
    "Put breakpoint here and check the final table which is displayed
  ENDIF.
ENDFORM.                    "USER_COMMAND

Thanks

I did set a check column in my data table as the first column. My problem is when I check the CHECK colum or change the other column's value and click the button created by me, it didn't update to the internal table.

After I debugged in the subroutine of USER_COMMAND, and check the value of the internal table g_t_alv, which is the data souce of REUSE_ALV_GRID_DISPLAY. I found Whatever the user click the checkbox , input or change the value in the ALV , the result will never update to the data internal table when I click the button created by myself. But when I click the standard button 'SAVE' , which is next to the TCODE input, all the changes made by user can update to the internal table.

It is the problem of the update of the ALV data. Why the standard SAVE button update all the changes to the internal table , but not my customized button .

It has nothing to do with SELFIELD-REFRESH = 'X', it is the internal table can not be updated ,but not the ALV display result didnot be refleshed.

I solved this problem...by adding the following code to update the internal table in the USER_COMMAND subroutine.

Thanks everyone~

DATA: gd_repid LIKE sy-repid, "Exists

ref_grid TYPE REF TO cl_gui_alv_grid.

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.
