Answer / anonymousabapdeveloper

Let us not confuse ourselves with user exits and customer exits. They are not the same. If you are referring to user exits - these are subroutines in a subroutine pool which provide an SD transaction a way to enhance its standard logic. You need an SAP access key to implement them. In a user exit, you can manipulate all the global data in the standard program.

Customer-exits on the other hand are function modules which follows naming convention EXIT_<program name>_<3 digit suffix>. Customer exits are grouped into Enhancement IDs which can be displayed in transaction SMOD. Customer exits can be activated/deactivated using a project in CMOD. Customer exits are called using CALL CUSTOMER-FUNCTION '<3 digit suffix>' but can also be called using ABAP statement CALL FUNCTION 'EXIT_<program name>_<3 digit suffix>'.
The difference between these two calls is only the latter implicitly checks if the customer exit is active or not.

BADI or business add-in is an enhancement based on ABAP objects. It benefits from the concept of polymorphism which allows it to have more than 1 implementation if defined as multi-use. The first two enhancements cannot.
