ALV Grid Displaying Problem

[Former Member]

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??

[Former Member]

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>.

Hi,

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

Thanks.

[Former Member]

Ryan,

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

[Former Member]

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

[Former Member]

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

[Former Member]

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

[RichHeilman]

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>

Regards,

Rich Heilman

[RichHeilman]

Are you seeing column headings?

Regards,

Rich Heilman

[Former Member]

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

[RichHeilman]

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,

Rich Heilman

[Former Member]

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?

[Former Member]

HI,

Your program should work, if you do the following changes,..

First of all remember that whenever you choose the specify the screen field name in the program, it should always be in CAPITAL Letters.

1st Change

So, Instead of

g_container TYPE scrfname VALUE 'Incentives ALV',

use

g_container TYPE scrfname VALUE <b>'INCENTIVES ALV'</b>,

(avoid using spaces in the name)

2nd change

instread of

CREATE OBJECT g_custom_container

EXPORTING container_name = 'g_container'.

use

CREATE OBJECT g_custom_container

EXPORTING container_name = <b>g_container</b>.

Regards,

Vara

[Former Member]

Rich,

Good thought !! That would cause an empty screen.

[RichHeilman]

John, it definitly did in my case, i had to change this in my screen flow logic due to his module names. I assumed that it was ok in his screen logic though.

Regards,

Rich Heilman

[RichHeilman]

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>.

Regards,

Rich Heilman

[Former Member]

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

[Former Member]

Ryan,

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

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

[RichHeilman]

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

Regards,

Rich Heilman

[Former Member]

Go into Screen Painter (SE51) for screen 100, click on the Custom Container object. What name appears in the upper left of the screen as the Object name. It MUST be G_CONTAINER in your example.

[Former Member]

What have you called the grid space in your screen. If it is not G_CONTAINER, then you must call what you have stated in screen painter and have the same name as the name of the variable in your data declarartion.

[RichHeilman]

Just another guess, make sure that your screen flow logic looks like this.

process before output.

  <b>module pbo.</b>

process after input.

  <b>module pai.</b>

Regards,

Rich Heilman

[Former Member]

Ryan,

To that point, set a breakpoint at one of the CREATE OBJECT statements. Are you stopping on those statements? Watch the ABAP error handler...

[Former Member]

Thanks for everyones help, I will rewards points for sure! I will try these ideas! Thanks again.

[Former Member]

I'm sure its the empty space being shown, but I'm not seeing the custom container button in se51..

[Former Member]

In SE51, you must click on the "Custom Control" object in the left hand box. Drag it over to the screen space and place it on the screen. Give it the object name of G_CONTAINER.

Now compile and execute.

[Former Member]

Works great, thanks everyone!

[RichHeilman]

So what was the problem, you never created the control on the screen in screen painter?

Regards,

Rich Heilman

[Former Member]

Yes, I did not create the control on the screen. That was all. Good learning experience though. Thanks again!

[Former Member]

Ryan,

The actual G_CONTAINER screen object IS the container for the ALV Grid object.

The Custom Control (G_CONTAINER) must exist as a physical entity on the screen; and the ALV Grid object reference must be bound to the Custom Control using the CREATE OBJECT (as you are doing now).

Glad it works for you now.

[RichHeilman]

.......Banging head against wall.........

.....this really hurts..........
