ALV Grid Displaying Problem

Former Member — Mon, 24 Jul 2006 19:02:58 GMT

I am using a simple Itab to load into my ALV display. The container is showing its screenname I've given it. But the ALV grid will not display. The Screens are activated and I'm using the proper structure with my Itab. Any Ideas??

Hi,

Can you post the code?

I guess there is some problem in the initialisation of custom container.

The component names in my structure are in all capitals.

hi ,

Instead of

CREATE OBJECT g_custom_container

EXPORTING container_name = 'g_container'.

use

CREATE OBJECT g_custom_container

EXPORTING container_name = <b>'G_CONTAINER'</b>.

Vara

Hi,

I tried the uppercase container_name, did not work, any other ideas would be greatly appreciated!

Thanks.

Ryan,

Please re-clarify your expected output. Are you expecting titles in the ALV grid?

Re: ALV Grid Displaying Problem

Former Member — Tue, 25 Jul 2006 14:36:16 GMT

My actual ALV Grid(rows/columns) is not displaying, I see only the container name at the top of the screen. I have my GUI Status and GUI Title are named MAIN100, My screen is 0100. Everything is activated. Any thoughts? Thanks

Re: ALV Grid Displaying Problem

Former Member — Tue, 25 Jul 2006 14:46:57 GMT

In the actual screen itself (in Screen Painter), is the Custom Container named 'G_CONTAINER' ? It needs to be (with your code example).

Re: ALV Grid Displaying Problem

Former Member — Tue, 25 Jul 2006 14:47:54 GMT

Also - G_CONTAINER must be in CAPS in your CREATE OBJECT statement.

Re: ALV Grid Displaying Problem

RichHeilman — Tue, 25 Jul 2006 14:51:44 GMT

Not sure if this makes a difference or not, but try adding brackets to the itab name also.




CALL METHOD g_grid->set_table_for_first_display
EXPORTING
i_structure_name = 'ztestincstructure'
is_layout = gs_layout
CHANGING
it_outtab = <b>incent_itab[].</b>

RichHeilman — Tue, 25 Jul 2006 14:52:24 GMT

Are you seeing column headings?

Re: ALV Grid Displaying Problem

Former Member — Tue, 25 Jul 2006 14:57:50 GMT

The brackets did not help, no column headings either, just seeing a blank screen with the title (Incentives Display)

Re: ALV Grid Displaying Problem

RichHeilman — Tue, 25 Jul 2006 14:59:42 GMT

How about making the structure name upper case. Do you see the ALV buttons in the screen?

CALL METHOD g_grid->set_table_for_first_display
EXPORTING
<b>i_structure_name = 'ztestincstructure'</b>
is_layout = gs_layout
CHANGING
it_outtab = incent_itab[].

Regard,

Ryan,

Also - make sure that your STRUCTURE name is in CAPS in the set_table statement.

Also - remove the data declaration of g_container.

Is your custom container called "G_CONTAINER" as menetioned above?

Re: ALV Grid Displaying Problem

RichHeilman — Tue, 25 Jul 2006 15:12:32 GMT

I got your program working just by capitalizing the container name. No other changes required. Plus, as mentioned, there is no need for the G_CONTAINER data statement.

CREATE OBJECT g_custom_container
          EXPORTING
                container_name = <b>'G_CONTAINER'</b>.

Rich Heilman

When I capitalize the container name, I'm still getting no display.. Thanks for all of your help!

This is ESSENTIAL to making the ALV Grid appear !!!

Re: ALV Grid Displaying Problem

RichHeilman — Tue, 25 Jul 2006 15:22:31 GMT

As john said, the container defined in the screen itself, but be name as G_CONTAINER, please check this.
