USER EXITS->
1. Introduction:
User exits (Function module exits) are exits developed by SAP.
The exit is implementerd as a call to a functionmodule.
The code for the function module is writeen by the developer.
You are not writing the code directly in the function module,
but in the include that is implemented in the function module.
The naming standard of function modules for functionmodule exits is:
EXIT_<program name><3 digit suffix>
The call to a functionmodule exit is implemented as:
CALL CUSTOMER.-FUNCTION <3 digit suffix>

CUSTOMER EXITS->
As of Release 4.6A SAP provides a new enhancement technique, the Business Add-Ins.
Among others,
this enhancement technique has the advantage of
being based on a multi-level system landscape (SAP, country versions, IS solutions, partner, customer, and so on)
instead of a two-level landscape (SAP, customer) as with the customer exits.
You can create definitions and implementations of business add-ins at any level of the system landscape.
To unify enhancements of the SAP Standard you can migrate customer exits to business add-ins.
