Thanks for your replies

I have checked posts you've write. I have use the code on my program, but when I run it in background the job is canceled with this error: OBJECTS_NOT_CHARLIKE. The error is on set_table_for_first_display method

I think I have used the code on the right way. Here I put my code:

DATA: grid1 TYPE REF TO cl_gui_alv_grid,

custom_container1 TYPE REF TO cl_gui_custom_container,

or_doc TYPE REF TO cl_gui_docking_container.

[...]

IF custom_container1 IS INITIAL.

IF cl_gui_alv_grid=>offline( ) IS INITIAL.

create a custom container control for our ALV Control

CREATE OBJECT custom_container1

EXPORTING

container_name = 'CONTAINER1001'.

create an instance of alv control

CREATE OBJECT grid1

EXPORTING

i_parent = custom_container1.

ELSE.

create an instance of alv control

CREATE OBJECT grid1

EXPORTING

i_parent = or_doc.

ENDIF.

PERFORM catalogo_campos. "Here I fill fieldcatalog table wt_fieldcatalog

PERFORM definir_layout. "Here I fill layout structure wt_layout

CALL METHOD grid1->set_table_for_first_display

EXPORTING

is_layout = wt_layout

CHANGING

it_outtab = wt_listado[]

it_fieldcatalog = wt_fieldcatalog.

ENDIF.

Thanks and regards

Dani

Hey Daniel,

This is late reply, I think what I know I should tell you.

ALV report cannot work in Background. I mean you cant use the ALV functionality in the background.

Actually GUI is not working in background. So ALV gives such error.

So don't write logic to create custome control(If it is in background)

Do you want to check my code whic is working

Create the controls the first time through

if gv_controls_created is initial

and sy-batch <> 'X'.

PERFORM create_controls.

endif.

Create the ALV grid for the data section

if gr_alvgrid is initial.

PERFORM create_grid.

else.

PERFORM refresh_alv_display.

endif.

Hi,

We can run alv grid in background.If we implement with

classes.Without class grid act as a list in background.

ALV Grid implemented based on class cl_gui_alv_grid CAN BE run in background. You have to use docking container.
