ALV Class

Former Member — Tue, 16 Jan 2007 08:32:49 GMT

Hello,

Is there any class that allows me to create an Editable ALV ?, I want to simulate a table maintenance, but instead of doing a table control, i´d like to do it with OO.

Any ideas and sample??

Thanks!!

Hi,

You need to use class cl_alv_gui_grid.In this while calling the method set_table_for_first_display,you nee to pass parameters for fieldcatalog.In that make the particular field as edit = 'X'.

Check these links.

Hello,

Here is a sample code for editable ALV:

The class used is cl_gui_alv_grid.

Define a container in the screen and name it CONTAINER.Also set the pf status of the screen and assign function codes for SAVE,BACK and EXIT.

In the field catalog,by defining the field as editable,you can get an editable ALV.

Further,to save the changes made in the ALV,you need to handle the user command for SAVE button.

Report SAMPLE.

DATA: ALV type ref to cl_gui_alv_grid,

cont type ref to cl_gui_custom_container,

ok_code type sy-ucomm,

i_spfli type table of spfli,

l_valid type c.

wa_fld type lvc_s_fcat.

Hi,

You have to do followiing things to make the ALV editable.

1) You have to modify the field Catalog fields to set the field EDIT as 'X'.

2) Call the method

CALL METHOD ALV_GRID_INSTANCE->set_ready_for_input

EXPORTING

i_ready_for_input = 0. ( For Display ) and '1' for Edit )

Put this after the set_table_for_first_display method.

3) If you want to check if the user has entered any value on the grid, use the Method : CALL METHOD ALV_GRID_INSTANCE->check_changed_data.

This will reflect as a change in your existiing data table to new data added on the editable grid.

Hope this helps..
