Fill in your table name and fiel name to download.

Also, Check out the sample program BCALV_EDIT_01.

The main steps are.

Step 1. Create a custom container that holds the grid.

CREATE OBJECT G_CUSTOM_CONTAINER
           EXPORTING CONTAINER_NAME = G_CONTAINER.

Step 2. Create teh grid object.

CREATE OBJECT G_GRID
           EXPORTING I_PARENT = G_CUSTOM_CONTAINER.

Step 3. Select your data.

SELECT * FROM SFLIGHT INTO TABLE GT_OUTTAB UP TO G_MAX ROWS.

Step 4. Pass the internal table to the method set_tble_for_first_display.

CALL METHOD G_GRID->SET_TABLE_FOR_FIRST_DISPLAY
         EXPORTING I_STRUCTURE_NAME = 'SFLIGHT'
                   IS_LAYOUT        = GS_LAYOUT
         CHANGING  IT_OUTTAB        = GT_OUTTAB.
