What are the types exits in SAP?

There are several different types of customer exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.


• 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

Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special sunscreen areas on a standard R/3 screen and calling a customer sunscreen from the standard screen’s flow logic.

• Function Module Exits

Function module exits add functions to R/3 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.
