To refresh the ALV grid display

[Former Member]

Hi,

I have craeted a report which displays the contents of the database table in ALV. on the application toolbar of that alv display, i've given a button to insert new record in that database table by calling a screen to enter new record. when i press that button and enter the details for new record , that record gets saved in database table but its not displaying in the ALV.

i need to press refrsh button manually.

Is there any way to refresh the ALV as soon as i press OK to save the record..

***make sure i m using Grid display.

No object oriented replies please.

Regards

Puja.

Hi,

if your grid is named grid1 you can do it in the end of pai by

CALL METHOD grid1->refresh_table_display.

Hi,

This is how you refresh the list after the user user command is executed.

set the field refresh of the rs_selfield to 'X'

rs_selfield-refresh = 'X'.

SELECT * FROM SFLIGHT INTO TABLE GT_SFLIGHT.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

I_PROGRAM_NAME = sy-repid

HI

call method refresh_table_display of class cl_gui_alv_grid.

The following method call is used to refresh the data displayed within an ALV object grid:

CALL method gd_tree->REFRESH_TABLE_DISPLAY.

CALL METHOD gd_tree->set_table_for_first_display

EXPORTING

is_layout = gd_layout

CHANGING

it_fieldcatalog = gd_fieldcat

it_sort = it_sortcat

it_outtab = it_report.

CALL method gd_tree->REFRESH_TABLE_DISPLAY.

CALL METHOD cl_gui_cfw=>flush.

I have copied one sample code ..even u can use this piece of code :

Content and Structure Change

Use

You are able to change the internal data table in various ways. Depending on which type of change you use, you have to proceed differently to make the change visible on the front end in the ALV output as well.

You are able to make the following changes:

· You change content or the sequence of the individual data records

Afterwards you need to refresh the ALV output

· You replace the entire data table

Refresh Display of the ALV Output

If you have changed single values, added rows or deleted rows in the data table of list-type ALV outputs, you need to complete these changes in the ALV output as well by refreshing the ALV display.

For Changes in the Tree Structure you do not have to refresh the display. In the other ALV tools, you do not have to refresh the ALV output when you make the following changes:

§ Changes to the Display of Columns

§ Changes Sequence of Columns in the ALV display

§ Changes to the DDIC Reference of Columns

By default, the ALV output automatically scrolls to the beginning. However, you are able to determine that the current display (position on the screen) not be changed.

You are able to refresh the ALV output in two ways:

· All settings for filters and sorting remain.

This setting can lead to newly inserted data records not being displayed because the filter setting hid exactly these data records.

· All settings for filters and sorting remain.

Features

For changes to content and structure, you are able to make the following settings:

· Refresh ALV output

· Swap the data table of the ALV output

Refresh ALV output

With the refresh, you ensure that the changed values are available on the front end as well.

Change the Structure of the Data Table with SET_DATA

Depending on which ALV tool you are using, the parameters of the SET_DATA method are different:

If you assign a new structure with SET_DATA, all objects that referred to the previous structure will be deleted such as all sort objects in list-type ALV outputs or all node objects in tree structures.

Hi,

Check the below FM:

DATA REF1 TYPE REF TO CL_GUI_ALV_GRID.
        CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
             IMPORTING
                  E_GRID = REF1.
        CALL METHOD REF1->CHECK_CHANGED_DATA.
