Are these SAP forums just useless one way or another? This one has all 3 links that are broken, or don't lead to anywhere useful...and one of the links just leads to a site without SSL.

Hi,

1.userexits are used inSD module only but customer exits are in SD, MM and PP also

User Exits are "form-based" custom enhancements.

Customer Exits are Function Module-based custom enhancements.

User Exit

1. Implemented as Subroutines.

2. Created in SAP namespace.

3. You require access key to make changes

Customer Exit

1.Implemented as FM.

2. Created in customer namespace.

3. Do not require access key to make changes.

2.Difference between user exits & customer exits:

User exit - A user exit is a three character code that instructs the system to access a program during system processing.

SXX: S is for standard exits that are delivered by SAP. XX represents the 2-digit exit number.

UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number

Customer exit - 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.

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 own source code in it. this is an enhancement. This doesnot affect sap std source code.

user exits are empty sub routines that the sap provides . you can fill it with your own source code. this is a modification. this affect the source code.

user exits means there is need of access key, as we are going to modify the sap std. code. whereas customer exits don't need access keys.

Eg: go to any sap std. pgm.Go to edit menu->find next->find for call cutomer-function. you can see different call customer-functions ...these are customer exits.

in some pgms u can see perform userexit_.....these are user exits.

Customer exit - The R/3 enhancement concept allows you to add your own functionality to SAPu2019s 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 maintained with transaction CMOD. They are constructed in such a way that all development is in the customer name range, so no access keys are required.

This is the best answer I could find and I can't give kudos to this answer for whatever reasons.

These r the main differences between user exits and customer exits

1) user exits r subroutines where as customer exits r function modules

2) user exits r not upgraded where as customer exits r will upgrade

3) customer exits r used for creating and additional fields or menu items to stadard tcode where as user exits r used for enabling or disabling the fields on the standrd screen or concatenating the key fields,it is not used adding an additional componenats to stadard tcode

4) customer exits r reusable where as user exits r not reusable.

Also:

1. Customer exits: Implemented as Function Modules within z includes. Anybody can change it and no access key is required.

2. User Exit: Implemented as subroutines within includes (any include except y or z includes). You need access for the specific include and then you can any subroutine (user exit) within that Include.

BADIs are the enhanced version of user exits where the same logic is implemented via classes and object (OOP)

Enchancement point is the latest once introduces with ECC6.0 . Not very sure about that but you can change it without any access key.

Please go through the following link which will help you understand the exits in a much better way:

1. Previously there were only user-exits.

2. Then came the concept of customer-exits.

3. user exits were nothing but subroutines

FORM/PERFORM

called from standard programs.

4. The FORM defintion was placed inside

an empty include file.

5. So It was called EVERYTIME.

and we need to MODIFY/REPAIR the

standard include .

6. Then it came with concept of customer-exit

7. It consists of calling a FUNCTION MODULE,

which is called only if

the user-exit is ACTIVATED (other wise not called)

In this case, the code in put inside

a pre-defined Z include.

8. Functionality of both is same, howerver

we can note the following important differences

a) Customer exit is called only if activated.

(hence, it does not waste resources)

b) in customer exit, REPAIR does not happen

to the standard include.

Exits are basically the hooks whcih SAP has provided to add your own code.

User Exits: These are provided only SD module .

They are Empty subroutines with naming like USEREXIT_.

We need to have Access key to implement them.

Customer Exits: These are enhancement techniques.

There are defined in SMOD and implemented in CMOD.

Types of Customer exits: Function exit, Screen Exit, Menu exit.

User Exit and Customer Exit are same ,but SAP Exit and Customer exit are different...

Customer Exit,

Enables you to determine values for variables by means of Functional Module exit.The function module used is EXIT_SAPLRRSO_001.

Create a project in CMOD by selecting the SAP Enhancement RSR00001 and assign this to the enhanced proj and activate it.

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

http://help.sap.com/saphelp_nw04/helpdata/en/1d/ca10d858c2e949ba4a152c44f8128a/frameset.htm

SAP EXIT:this processing type contained in variables that are delivered with SAP BW business content.

http://help.sap.com/saphelp_nw04/helpdata/en/1d/ca10d858c2e949ba4a152c44f8128a/frameset.htm

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

reward points if found useful
