difference between customer exits and user exits

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>

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

which gives the list of exits for a tcode

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.

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

designed for all modules
