CL_SALV_TABLE : ALV Object Model – Display ALV Table

Use the below steps to display simple table using ALV Object Model (Class CL_SALV_TABLE).

  • Declare an internal table and fill the internal table with required data.
  • Generate an instance of the ALV table object
  • Display the ALV table.
*&---------------------------------------------------------------------*
*& Data Declaration
*&---------------------------------------------------------------------*
DATA: gt_spfli TYPE TABLE OF spfli.
DATA: gr_table TYPE REF TO   cl_salv_table.

*&---------------------------------------------------------------------*
*& Start-of-Selection
*&---------------------------------------------------------------------*
START-OF-SELECTION.
  SELECT * UP TO 10 ROWS FROM spfli INTO TABLE gt_spfli.

*Generate an instance of the ALV table object
  CALL METHOD cl_salv_table=>factory
    IMPORTING
      r_salv_table = gr_table
    CHANGING
      t_table      = gt_spfli.

*Display the ALV table.
  gr_table->display( ).

Output

sap-alv-object-model-display-table-1

You can display the simple ALV table in the following ways:

  • As a classic ABAP list : In order to display as classic ABAP list, just set the LIST_DISPLAY parameter as TRUE in the factory method of CL_SALV_TABLE.
  • As a table control

    Here, there are also two options:
    • Full screen table (ALV Grid) : As default the ALV will be displayed as ALV grid as shown in the above example
    • in a SAP-GUI container

      You generate a container of the class CL_GUI_CONTAINER in your screen. The table is displayed in this container. You can use this type of table, for example, to display multiple tables on the screen or to mix with other SAP Enjoy Controls. For this option use R_CONTAINER and CONTAINER_NAME parameters in the factory method of CL_SALV_TABLE.

Below code displays simple table as classic ABAP list.

*&---------------------------------------------------------------------*
*& Data Declaration
*&---------------------------------------------------------------------*
DATA: gt_spfli  TYPE TABLE OF spfli.
DATA: gr_table  TYPE REF TO   cl_salv_table.

*&---------------------------------------------------------------------*
*& Start-of-Selection
*&---------------------------------------------------------------------*
START-OF-SELECTION.
  SELECT * UP TO 10 ROWS FROM spfli INTO TABLE gt_spfli.

*Generate an instance of the ALV table object
  CALL METHOD cl_salv_table=>factory
    EXPORTING
      list_display = if_salv_c_bool_sap=>true
    IMPORTING
      r_salv_table = gr_table
    CHANGING
      t_table      = gt_spfli.

*Display the ALV table.
  gr_table->display( ).

Output

sap-alv-object-model-display-table-2
