Basics

If we want to create an ALV first, we need to declare a local variable of type references to the cl_gui_alv_grid class, a variable of type references to the cl_gui_custom_container class, and a local constant with the name of the container and the table where we store data that will be shown on screen:

DATA: lt_spfli      TYPE TABLE OF spfli,      lr_alv        TYPE REF TO cl_gui_alv_grid,      lr_ccontainer TYPE REF TO cl_gui_custome_container. CONSTANTS: lc_container_name TYPE scrfname VALUE 'ALV'.

In the Flow Logic tab, create the PBO and PAI modules as follows:
