classes required,
cl_gui_custom_container
cl_gui_alv_grid
cl_gui_custom_container:This control hosts other controls in a logical collection and provides a physical area for displaying them.
You can display logo on your screen using the custom control function. A custom control is an area on the screen, created using the screen painter. To link a custom control to a container control, pass the custom control name to the CONTAINER_NAME parameter of the container control constructor when you instantiate it.
Eg: container EXPORTING container_name = u2018CONTAINER'
cl_gui_alv_grid:
1. CONSTRUCTOR : Generate an instance of the ALV Grid Control.This method is called automatically if you use CREATE OBJECT to create an object of class CL_GUI_ALV_GRID .
When the control is generated, it is created on the frontend and linked to a container control.
2. set_table_for_first_display : Display an output table in the control. Display an output table in the ALV Grid Control instance. In the call sequence, you must specify either a reference structure of the Data Dictionary or a suitable field catalog. Before execution, you can use optional parameters to load a layout, sort the table by fields, set a filter for columns and define properties of the grid control.
3. REFRESH_TABLE_DISPLAY : Refresh the data displayed in the control .You use this method to refresh the output table in the grid control. This is necessary if you change the display of the data by means of methods (for example, using set_frontend_layout), or if you want to display new data selected in the same ALV Grid Control.

Vijetha.
