Control Framework: Fatal error - GUI cannot be reached

[Former Member]

Hi to all,

Situation:

I have created a transaction which uses a lot of

Grids bases on class: CL_GUI_ALV_GRID.

Problem:

Now I want to create initial data calling this transaction in BACKGROUND-TASK!

Error:

If I do this, following error occurs:

Control Framework: Fatal error - GUI cannot be reached

How can I avoid this error?

Thanks a lot in advance

Hi,

insert foll. lines before starting grid:

CALL METHOD cl_gui_alv_grid=>offline
                RECEIVING e_offline = off.
    IF off IS INITIAL.
      CREATE OBJECT g_custom_container
             EXPORTING container_name = g_container.
    ENDIF.

Thanks a lot for Your solving,

i have done similar to your suggestion.

I am checking SY-BATCH <> 'X', before

creating the controls.

But anyway, your way is much more elegant!
