Hi,

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

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.

In ALV FM for list display,

use parameter callback user command,

inside the form for that subroutine

use

selfield-refresh = 'X'.

Reward if useful.

Hi Navi,

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.

Hope this helps.

Reward if helpful.

Sipra
