ALV By CL_SALV_TABLE Class

 

• CL_SALV_TABLE class is a part of ALV object model.
• ALV object model is an encapsulation of the pre-existing ALV tools
• In simple terms CL_SALV_TABLE actually combines both the CL_GUI_ALV_GRID class for container implementation, as well as the REUSE_ALV_GRID_DISPLAY and REUSE_ALV_LIST_DISPLAY function modules for full screen display.

Advantage :-

• It provides a collection of interface for ALV tools.

Disadvantage :-

• We can not go for editable ALV using ALV object model.
