ALV Trouble

[Former Member]

Hey folks, I cant get anything into my ALV.

Its driving me crazy because I cannot find any mistake in my coding.

Help would be awesome! Thanks in advance!

If the container is initial it should get filled with the content in gt_titel (definitely filled),

otherwise it just gets refreshed.

top include :

data: go_container type REF To cl_gui_custom_container,
      go_alv_grid type REF TO cl_gui_alv_grid.

module itself

MODULE status_0100 OUTPUT.

  IF go_container IS INITIAL.
    CREATE OBJECT go_container
      EXPORTING
        container_name = 'CONTROL_AREA_1'.

    CREATE OBJECT go_alv_grid
      EXPORTING
        i_parent = go_container.

    CALL METHOD go_alv_grid->set_table_for_first_display
      EXPORTING
        i_structure_name = 'zlars'            ***created a DDIC structure containing all required attributes.***
*!!!!!!
      CHANGING
        it_outtab        = gt_titel.

  ELSE.
    CALL METHOD
      go_alv_grid->refresh_table_display.
  ENDIF.

Change below one to CAPS.

i_structure_name = 'zlars'        " Change it to 'ZLARS'

doesnt help, sry 😕

1. Check whether the custom container name in screen matches with below name in program,

 container_name = 'CONTROL_AREA_1'. 

2. In debugging put a breakpoint before CALL METHOD go_alv_grid->set_table_for_first_display and check whether inernal table

gt_titel is getting filled.

3. Also check whether you called the screen and the screen is active.

Hello Paul,

Please post the full code .

Are you able to see the AVL list output with empty table or nothing gets displayed during program execution?

Are you populating the internal table "gt_titel" properly?

Did you check in debug mode the contents at the method "set_table_for_first_display"?

Thanks,

Greetson

I don't see anything wrong. you need to troubleshoot it.

1) Can you see the GRID (even without data) - If no, make sure you have container drawn and named CONTROL_AREA_1

If you can see the grid but no data...

I would put a break point before call to 'CALL METHOD go_alv_grid->set_table_for_first_display' then check if you have the data in internal table

If yes, Check the defination of internal table and match to the structure you are passing and also make the structure name to CAPS.

If the table is filled up but no display it mainly comes from the Dynpro...

in your dynpro check in the elementlist tab if ther is an element type 'CuCtr' named 'CONTROL_AREA_1'

This is the link between the container from the code and the Dynpro.

[Former Member]

ok, it had nothing to do with writing in caps or not.

I cannot see the grid when starting the program.

the element list contains a proper custom control.

somehow its still not working, maybe I'm just to dumb since Im an abap rookie...

this is the entire coding

Hi Paul,

Sorry for my stupid question.

Does gt_titel have the same structure of ZLARS?

Regards,

Filippo

Edited by: FCannavo on May 25, 2011 11:23 AM

[Former Member]

gt_titel has everything what tsad2 (database table) has, ZLARS is structured like a line of tsad2.

so yes

[SuhaSaha]

Looks like you've commented the CALL SCREEN statement

*CALL SCREEN 100.

[kesavadas_thekkillath]

Why have you commented this ???

*CALL SCREEN 100.

[frederic_r]

You have to build up the field catalog for the alv Grid ( say which fields have to be displayd) and send it in the method set_table_for_first_display...

[Former Member]

Hi,

Uncomment the Call Screen and check whether the screen is activated or not ?

[Former Member]

Oops, but that was just because I tried something out, originally it had not been commented out

Going to try that field catalogue issue, thats what a colleague recommended too

[Former Member]

super cool, I tried it with the patterns 'REUSE_ALV_FIELDCATALOG_MERGE' and 'LVC_TRANSFER_FROM_SLIS' to fill the field catalog with data and now it works smoothly

thanks to everybody for help!
