REUSE_ALV_GRID_DISPLAY

This function allows you to create an ALV. It can be used as an alternative to SALV and ALV OO (Object-Oriented ALV). It's particularly useful when you need to simply manage calls to other external processes that should overwrite the current screen (e.g., calling a PDF form).
