Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.

As with customer exits two different views are available:

In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.

In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.

In contrast to customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.

BADI's can be used any number of times, where as USER-EXITS can be used only one time.

Ex:- if your assigning a USER-EXIT to a project in (CMOD), then you can not assign the same to other project.

There are three generations of user-exits in SAP ABAP now.

First generation: there had been empty subroutines in place in the coding where you could add your code. However, this required to modify code of SAP standard programs. Example: search for forms starting USEREXIT.. in SAPMV45A

Second generation: CUSTOMER-FUNCTION. In certain places of SAP standard code there are calls CALL CUSTOMER-FUNCTION ‚001' . These routines can be defined with SMOD edited with transaction CMOD.

Third generation: using ABAP objects instances, they are called BADI. They are call with CALL METHOD (instance) .... they are created with transactions SE18/SE19. To find BADI search for the word EXIT_HANDLER in the coding.
