ALV GRID without using Screen.

arpita_churi3 — Thu, 31 Jul 2014 05:12:56 GMT

Hi All,

I have developed one report in which i am using ALV OOPS concept to dipsplay the report

data.

I am using following code:

Calling the method of global class as follow:

method:

   CREATE OBJECT o_alv
    EXPORTING
      i_appl_events = 'X'
      i_parent      = v_custom_container.

    IF i_fieldcat IS NOT INITIAL.

    v_variant = sy-repid.

    CALL METHOD o_alv->set_table_for_first_display
*      EXPORTING
*        is_layout                     = v_layout
*        i_default                     = 'X'
*        i_save                        = 'U'
*        is_variant                    = v_variant
      CHANGING
        it_outtab                     = i_inventory[]
        it_fieldcatalog               = i_fieldcat[]
      EXCEPTIONS
        invalid_parameter_combination = 1
        program_error                 = 2
        too_many_lines                = 3
        OTHERS                        = 4.

I_inventory[] and i_fieldcat[] contain data but it is not displaying the grid.I dont want any screen in report.

Thanks,

Arpita

REUSE_ALV_GRID_DISPLAY and CL_SALV_TABLE are both calling screens as well, the calls are just wrapped inside so you don't have to do it explicitely.

You can't do this without a screen.

Either you can follow this. Here no need to create any custom container in screen 100.Just call it.

DATA lr_alv TYPE REF TO cl_gui_alv_grid.

DATA lt_table TYPE TABLE OF t529a.

SELECT * FROM t529a INTO TABLE lt_table.

CREATE OBJECT lr_alv
EXPORTING
    i_parent = cl_gui_container=>screen0.

CALL METHOD lr_alv->set_table_for_first_display
EXPORTING
    i_structure_name = 'T529A'
CHANGING
    it_outtab        = lt_t529a

CALL SCREEN 100.

Hi Arpita,

Try my code.Please notice the write statement in the last line.

You can use write to activate the standard screen so that you needn't create a new screen.


DATA: l_alv TYPE REF TO cl_gui_alv_grid ,
       lt_bkpf TYPE TABLE OF bkpf .

 SELECT * FROM bkpf UP TO 10 ROWS INTO TABLE lt_bkpf.

 CREATE OBJECT l_alv
   EXPORTING
     i_parent = cl_gui_container=>screen0.

 CALL METHOD l_alv->set_table_for_first_display
   EXPORTING
     i_structure_name = 'BKPF'
   CHANGING
     it_outtab        = lt_bkpf.

 WRITE ' '.

Thanks,

Sam

Hi Arpita,

Where did you call the method SET_TABLE_FOR_FIRST_DISPLAY???

This method should be called in PBO of the screen. And even you have create a container and include that container in the ALV object (CL_GUI_ALV_GRID).

If ever you want to create ALV Grid without using screen and container, you need to use CL_SALV_TABLE.

Sample code to build ALV_GRID using CL_GUI_ALV_GRID is given below, please refer:

*&---------------------------------------------------------------------*

*& START-OF-SELECTION

*&---------------------------------------------------------------------*

START-OF-SELECTION.

* Fetching data from database into internal table to display

SELECT MATNR MAKTX FROM MAKT

WHERE MATNR IN S_MATNR

AND SPRAS = 'EN'.

*&---------------------------------------------------------------------*

*& END-OF-SELECTION

*&---------------------------------------------------------------------*

END-OF-SELECTION.

* Calling a screen to display ALV Grid

CALL SCREEN 100.

*&---------------------------------------------------------------------*

*& Module STATUS_0100 OUTPUT

Hi Arpita.

You can try this code to generate a simple and fast ALV report.


DATA: lr_alv          TYPE REF TO cl_salv_table,
     lr_alv_cols     TYPE REF TO cl_salv_columns,
     lr_alv_func     TYPE REF TO cl_salv_functions,
     lrx_salv_error  TYPE REF TO cx_salv_error.

TRY.
         cl_salv_table=>factory( IMPORTING r_salv_table = lr_alv
                                 CHANGING  t_table      = YOUR_TABLE_DATA ).

*      Configure columns
         lr_alv_cols = lr_alv->get_columns( ).
         lr_alv_cols->set_optimize( ).

*       Active all ALV functions
         lr_alv_func = lr_alv->get_functions_base( ).
         lr_alv_func->set_all( ).

         lr_alv->display( ).

       CATCH cx_salv_error INTO lrx_salv_error.

ENDTRY.

Regards.

You are the best. The WRITE statement works.
