Business Add-Ins are a new SAP enhancement technique based
on ABAP Objects. They can be inserted into the SAP System to

BADI is just an object-oriented version of user-exit.
Instead of entering program code into some function module
(as in customer-exit), you define some class which has to
implement predefined methods and those methods are fired at
predefined points just like an old user-exit. Some BADI can
have multiple independent implementations which is much
better for software deployment as several developers can
implement the same BADI independently.
