Demo program for TOP-OF-PAGE for ALV displayed through CL_GUI_ALV_GRID

This program demonstrates how to create TOP OF PAGE for an ALV grid displayed through CL_GUI_ALV_GRID. One interesting fact which may be considered here is that the splitter TOP-OF-PAGE is not called while printing or background spool and the TOP-OF-PAGE printed in the spool cannot be displayed in the foreground.

The TOP-OF-PAGE displayed in foreground (this TOP-OF-PAGE won't be printed):
