• They are system wide available and are not application specific.
• The ABAP workbench has large number of standard function modules.
• Function modules belong to a pool called function group.
• They have fixed interface for exchanging of data.
• The call function statement helps us to call a function module by its name.
• Function groups are the only program type that contains function modules.
• Function modules are used to be designed by other programs.
• For each and every function group <fgrp>, the system generated a main program as SAPL<fgrp>.
• These main programs contains include statements.
