Hi ,

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).

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.

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

User-exit doesnu2019t have any classification.

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

, menu exit.

User exits are Basically designed For SD module.

Costomer exits Are available for MM,SD,FI,HRu2026..Basically

designed for all modules.

While changing User-exit,Access Key is required, whereas in

Customer-exit no access key is needed

Hi,

The Differences are-

1.Userexits are delivered only once that is after upgradation

this subroutine does not exist, while customer exits exist.

2.user exits are only related to SD module and are

subroutines only,where as customer exits are the

function modules which are applicable for all the

modules.

3.USER EXITS ARE IMPLEMENTED USING SUBROUTINES

And CUSTOMER EXITS ARE IMPLEMENTED USING

FUNCTION MODULE WHICH HAS AN Z INCLUDE WHERE WE CAN WRITE

OUR OWN CODE

DIFFERENT TYPES OF CUSTOMER EXITS ARE

1.FUNCTION EXITS

2.MENU EXITS

3.SCREEN EXITS

4.TABLE EXITS OR CUSTOMER INCLUDES

User exits are basically modifications done to the std. pgm

for whic u need to have access code,this is not reccomended

in sap as during upgradation none of the mod. will come thru.

In contrast customer exits are enhancements done to the

std pgm in the space provided by sap so that during

upgrading versions this also will be available.

Customer exits types

Function exits, Field exits(absolete), screen exits.

Sujit
