2)Function Module Enhancements

Source code enhancements – Enhancements to the source code are carried out by means of ABAP source code enhancements.
Parameter interface enhancements – You can enhance the parameter interface of a function module with new, optional formal parameters as enhancement implementation elements.

3)Customer Exits(CMOD/SMOD)(Notes:As of Release 4.6, function module exits (customer exits for source code enhancements) were replaced with Business Add-Ins.)

There are several different types of customer exits.

Menu Exits

Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with “+” (a plus sign). You specify the menu item’s text when activating the item in an add-on project.

Screen Exits

Add screen layouts to applications. SAP creates screen exits by placing special subscreen areas on a standard screen and calling a customer subscreen from the standard screen’s flow logic.

Function Module Exits

Add functions to applications. Function module exits play a role in both menu and screen exits. When you add a new menu item to a standard pulldown menu, you use a function module exit to define the actions that should take place once your menu is activated. Function module exits also control the data flow between standard programs and screen exit fields.
SAP application developers create function module exits by writing calls to customer functions into the source code of standard programs. These calls have the following syntax: CALL CUSTOMER-FUNCTION ‘001’.
