Hi,

User exit are povided in FORMS by SAP and you need a ACCESS key to implement a user exit.

Customer exists are provided in FUNCTION MODULES by SAP and you dont need a ACCESS key to implement a customer exit.

1. User exits are called by SAP standard programs using PERFORM. where as Customer exits are called using CALL CUSTOMER FUNCTION.

2. User exits read and change almost any global data from host program where as Customer exits only acces your import/export/changing/tables parameters

3.very easy to manipulate erroneously global data in user exits where as Customer exits will never lead to inconsistency .

4.User exits doesn’t have any classification where as customer exits we have function-module exit , screen exit , menu exit

5. User exits are designed For SD module where as customer exits are basically designed for all modules.

6.User-exits can be written only using access-key where as No need of access key is required in customer exits.

7. Will not be there for next version unless modification assistance tool is used where as Customer-exits are not wiped during upgradation

regards,

vasavi.

reward if helpful.

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.

*****************

In order to find out the user exits for any tcode,

1. get the developement class of the tcode from SE93.

2. Now goto transaction SMOD and press F4,

3. give in the Deve class in the dev class and Press ENTER

this will show u the exits for any tcode.

or execute this report

http://www.erpgenie.com/sap/abap/code/abap26.htm

which gives the list of exits for a tcode

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

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.

SAP user exits (enhancement names that we see in SMOD transaction) are all stored in the table MODSAP. The field NAME contains the enhancement name and the field MEMBER contains the name of the function module that will be called if the customer enhancement exists and is active. The customer enhancement projects are stored in the table MODACT. There, the NAME field is the name of the project and MEMBER is the name of SAP enhancement (that from the MODSAP).

So, if you are in some include, you can use where-used-list to get to the function module name. Then you find the SAP enhancement name from the MODSAP by supplying the function module. And finally, you find the customer enhancement projects by querying the MODACT with the SAP enhancement in the field MEMBER.

Hi,

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.

The following document is about exits in SAP :-

1.USER EXITS are FORMS and are called by SAP standard programs

using PERFORM.

CUSTOMER EXITS are FUNCTIONS so they are called using CALL

FUNCTION (or more exactly CALL CUSTOMER FUNCTION).

2.Inside the form (user exit) you can read and change almost

any global data from host program.

Inside a function (customer exit) you can only acces your

import/export/changing/tables parameters.

3.User exits are more flexible because you have more

information to use in your code but on the other hand , it

is very easy to manipulate erroneously global data and lead

the standard program to a dump or even to make database

inconsistent.

Customer exits are more restrictive but you are sure any

change you can make to any parameters will never lead to

inconsistency

4.User-exit doesn’t have any classification.

In customer-exit we have function-module exit , screen exit

, menu exit.

5.User exits are Basically designed For SD module.

Costomer exits Are available for MM,SD,FI,HR…..Basically

designed for all modules.

REWARD IF USEFUL
