plz help.

1)why and When we use user-exits.what is the need to use user-exit,does we need access key while using user exit?

2)HOW many types of exits are there.

3)when we go to SMOD and and press F4 we can search three types of exits a)function,b)menu exit c)screen exit. if we have these three exits then why we need User exit? Please explain ,

Hi Zareen,

USER EXITS are FORMS and are called by SAP standard programs using PERFORM.

Inside the form (user exit) you can read and change almost any global data from host program.

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.

User-exit doesn ’ t have any classification.

Basically designed For SD module

User-exits can be written only using access-key

With user-exits the code , the developer has written will not be there for next version unless modification assistance tool is used

Costomer exits:

CUSTOMER EXITS are FUNCTIONS so they are called using CALL FUNCTION (or more exactly CALL CUSTOMER FUNCTION).

Inside a function (customer exit) you can only acces your import/export/changing/tables parameters.

Customer exits are more restrictive but you are sure any change you can make to any parameters will never lead to inconsistency

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

Are available for MM,SD,FI,HR…..Basically designed for all modules.

No need of access key

Customer-exits are not wiped during upgradation

USerExits:

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>

SMOD:

By using this transaction code we can find the Exits .

Cmod:

Here we can activate the exits after providing the logic.

********Rewards some points.

Customer exits and User exits are entirely different.

They don't have any relationship.

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 technically an enhancement.Eg for customer exits are Function module exits,Menu Exits,Screen Exits.

User exists are empty subroutines that the SAP Developers have provided for you that u can fill with your own source code.This is technically a modification since the object in the SAP name space is modified.

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.

Thanks,
