Use of User Exit

[Former Member]

Dear Gurus,

I have a doubt... regd. the User Exit...

Lot of standard user exits are there for SD..based on the requirement. As per our client requirement we found a particular User Exit... how to activate and use these user exits?

is there any particular process is there or we need to coordinate with ABAPer only..

Give me a breif idea about this...& if there is no standard user exit is not available, then how to create a user exit??

Thanks in Advance

Hi,

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.

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.

There are different types of customer exits like field exit,function module exit etc

Customer Exits & User-Exits are the user specific that

provides specific Functionality to Standard Functions.

SMOD ; is used to Find User Exits for diff Business Process

CMOD : is used to Implement exits.

Hope it helps u...!!!
