Hi,
For ALV GRID DISPLAY (using <b>OOPS</b>),
1)Create an object of the <b>container</b>(an instance of a class like cl_gui_custom_container).
2)Create an object of the <b>ALV using class cl_gui_alv_grid</b> and give the CONTAINER name that you define in your screen layout as the parent of the ALV.
3)Call the method <b>SET_TABLE_FOR_FIRST_DISPLAY</b> of the class cl_gui_alv_grid.
4)<b>Field catalog</b> is used when you want a variation of the standard structure to be displayed on your ALV.A  variable of table type <b>LVC_T_FCAT</b> is defined and variations can be made as per the requirements.The variable is then passed in the method SET_TABLE_FOR_FIRST_DISPLAY.
<b>A SAMPLE PROGRAM:</b>
