The R/3 enhancement concept allows you to add your own functionality to SAP’s standard business applications without having to modify the original applications. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks."

Customer exits are implemented in Z-includes and are ENHANCEMENTS to the system.

User-exits were firstly intended to be developed for the SD module. You make your coding in includes in SAP namespace (e.g MV*). That's why, user exits are MODIFICATIONS to the system. In includes for user exits there are empty subroutines ( generally with the name convention "userexit_...") and you code using global variables of the main program.

But, generally developers use these terms without this distinction. So, someone may mean a "customer exit" when (s)he says "user exit" or vice-versa.

hi,

Customer exits are provided to the customer in the form of Function Module which holds the include in the customer namespace.The user can add his/her own source code in it.Customer exits are implemented in Z-includes and are ENHANCEMENTS to the system.

Customer exit is called only if activated.

for customer exits, SMOD is the transaction code.

User exists are empty subroutines that the SAP Developers have provided for you that u can fill with your own source code.This is technically a modification since the object in the SAP name space is modified.

Hi,

A point in an SAP program where a customer's own program can be called.

In contrast to customer exits, user exits allow developers to access and modify program components and data objects in the standard SAP System. On upgrade, each user exit must be checked to ensure that it conforms to the standard system.

There are the following types of user exit:

User exits that use INCLUDEs -

These are customer enhancements that are called directly in the program.

User exits that use tables -

These are used and managed using Customizing.

Customer Exit

SAP creates customer exits for specific programs, screens, and menus within standard applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.

If you want to enhance the functionality of your SAP System, you should take advantage of the exits available in standard applications. There are two main reasons why you should use exits rather than modifying SAP software yourself. Add-ons attached to exits have the advantage that:

· They do not affect standard SAP source code

When you add new functionality to your SAP System using SAP’s exits, you do not alter the source code of standard SAP programs in any way. The code and screens you create are encapsulated as separate objects. These customer objects are linked to standard applications, but exist separately from SAP’s standard software package.

· They do not affect software updates

When you add new functionality to your SAP System using SAP’s exits, your objects (called customer objects) must adhere to strict naming conventions. When it comes time to upgrade a to a new software release, customer objects’ names ensure that they will not be affected by any changes or new additions to the standard software package.

Customer exits are not available for all programs and screens found in the SAP System. You can only use customer exits if they already exist in the SAP System. You find find more information about locating applications with pre-defined exits in Locating Applications that have Exits

User Exits:

User exits allow you to add additional functions to the SAP standard.

Programs with user exits contain subroutine calls at certain points in their syntax that are identified by the prefix USEREXIT. The actual user exits are located in an include that has been assigned to a module pool. This is where customers can include any changes (enhancements) that they want to make to the system. These includes are always processed during program flow.

Advantage: In principle, customers can modify anything they want that is found in the include (tables, structures, and so forth).

Disadvantage: SAP cannot check the individual enhancements themselves which often leads to errors in the enhancement process.

hi,

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 ❤️ digit suffix>

http://www.sap-img.com/abap/a-short-tutorial-on-user-exits.htm

CUSTOMER EXITS-> t-code CMOD.

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.
