Hi,

Class ALV Specification

Classes used:

CL_GUI_ALV_GRID

Example of ALV using Classes

DATA: lcl_alv TYPE REF TO cl_gui_alv_grid,

t_flights TYPE STANDARD TABLE OF FLIGHTS.

SELECT * FROM flights INTO TABLE t_flights.

CREATE OBJECT lcl_alv

EXPORTING I_PARENT = cl_gui_container=>screen0.

CALL METHOD lcl_alv->set_table_for_first_display

EXPORTING

I_STRUCTURE_NAME = 'FLIGHTS'

CHANGING

IT_OUTTAB = t_flights.

CALL SCREEN 100.

Example Details

This is a simple example of the class ALV, we do not need to create, in this case, a field catalog because we are using the whole table of FLIGHTS and we will show all the fields that this table contains, we do this at the I_STRUCTURE_NAME = 'FLIGHTS' statement.

The CL_GUI_ALV_GRID constructor needs the I_PARENT parameter to define where it will be show, in the example we set the entire screen to place the ALV.

Hi,

Here are a few classes used in ALV, just read through their documentation or look at how they've been implemented in your system and you'll get a good idea on how to use them:

CL_ALV_EVENT_DATA (Changing Data Container for Events)

CL_ALV_EVENT_TOOLBAR_SET (ALV Context menu)

CL_ALV_TABLE_CREATE (Dynamic Creation of ALV Data Table)

CL_ALV_TREE_BASE (Basis Class ALV Tree Control)

CL_CK_ALVTREE_NKEY_2_OBJECT (Converter Node Key Object)

CL_COST_COSTINGVERSION_ALV (Display Costing Versions)

CL_GUI_ALV_GRID (List Viewer)

CL_GUI_ALV_GRID_BASE (Basis Class for ALV grid)

CL_GUI_ALV_TREE (ALV Tree Control)

CL_GUI_ALV_TREE_SIMPLE (Simple ALV Tree)

Sample:


DATA: lcl_alv TYPE REF TO cl_gui_alv_grid,
      t_flights TYPE STANDARD TABLE OF FLIGHTS.

SELECT * FROM flights INTO TABLE t_flights.

CREATE OBJECT lcl_alv
    EXPORTING I_PARENT = cl_gui_container=>screen0.

CALL METHOD lcl_alv->set_table_for_first_display
    EXPORTING
       I_STRUCTURE_NAME = 'FLIGHTS'
    CHANGING
       IT_OUTTAB = t_flights.

CALL SCREEN 100.

Reward points if useful....

Hi,

see the examples here.

example1:


DATA:t_mara TYPE TABLE OF mara.
DATA:FCAT TYPE LVC_T_FCAT.

DATA:G_CONTAINER TYPE SCRFNAME VALUE 'TABC',"TABC is *container in screen 101
     GRID  TYPE REF TO CL_GUI_ALV_GRID,
     G_CUSTOM_CONTAINER TYPE REF TO CL_GUI_CUSTOM_CONTAINER.

set screen 101.

MODULE STATUS_0101 output.
  IF G_CUSTOM_CONTAINER IS INITIAL.
    CREATE OBJECT G_CUSTOM_CONTAINER   "CREATING OBJECT FOR CUSTOM CONTAINER
           EXPORTING CONTAINER_NAME = G_CONTAINER.
    CREATE OBJECT GRID    "CREATING GRID IN WRKBNCH SCREEN
           EXPORTING I_PARENT = G_CUSTOM_CONTAINER.
    CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
      EXPORTING
        I_STRUCTURE_NAME = 'MARA'
      CHANGING
        CT_FIELDCAT      = FCAT[].

    SELECT * from mara into table t_mara.

    CALL METHOD GRID->SET_TABLE_FOR_FIRST_DISPLAY
      CHANGING
        IT_FIELDCATALOG = FCAT[]
        IT_OUTTAB       = t_MARA.
  ENDIF.
ENDMODULE.

flow logic of screen 101:


PROCESS BEFORE OUTPUT.
 MODULE STATUS_0101.

PROCESS AFTER INPUT.
