FUNCTION 'REUSE_ALV_GRID_DISPLAY' - Fieldcat modify in user_command?

Clemenss — Fri, 06 Oct 2006 12:10:21 GMT

Hi,

with ALV function call, is it possible to modify the field catalog when processing the event form 'USER_COMMAND'?

The reason:

Before calling the display, I generate the field catalog. Then I set all unpopulated columns (field is initial in all lines) to 'TECH'. So I see only 'active' columns.

Now, the user can do some interaction which will change the lines values. In event routine for 'USER_COMMAND, I set the selfield-refresh = 'X'.

But now, for some fields, I want to remove the 'TECH' attribute of the field catalog because they get populated.

How to achieve this?

Regards,

Clemens

Hello ,

Under the the event USERCOMMAND you can modify the fieldcatalog but to see the result you will have the REUSE_ALV_GRID_DISPLAY again.

You don't need to call REUSE_ALV_GRID_DISPLAY again. Try REUSE_ALV_GRID_LAYOUT_INFO_GET/REUSE_ALV_GRID_LAYOUT_INFO_SET.

Ha!

Don't remember who gave me this hint - thank you so uch!

Function group SLVC_FULLSCREEN

hast the FMs

REUSE_ALV_GRID_DISPLAY,

REUSE_ALV_GRID_DISPLAY_LVC

and also

GET_GLOBALS_FROM_SLVC_FULLSCR

Here you have the exporting parameter E_GRID as a reference of current instance of CL_GUI_ALV_GRID.

You may use this to access all the methods as i.e. GET_FRONTEND_FIELDCATALOG and SET_FRONTEND_FIELDCATALOG

and whatever more you want.

Makes use of OO technology almost obsolete
